- Telegram, X, Meta. Different cases, identical cases.
Hidden censorship and refusal to cooperate. The news from the past few weeks has reignited the debate on online freedom of speech. However, the issue is quite different.
---
Who is responsible for the content published on social networks?
What should the role of platforms be in content moderation?
Who should be consulted in cases of disputes involving illegal content?
Should there be a limit to freedom of speech online? Where should the line be drawn?
These are just a few of the numerous questions that have characterized the debate for years, not only regarding social networks but, more broadly, the entire landscape of online interactions.
In recent weeks, tensions have reignited due to three cases that have stirred the pot—depending on the perspective—with slogans of either combating illegal activity or fighting censorship: Telegram, Meta, and X.
These cases are distinct, with the platforms and their executives behaving differently in each instance: Meta cooperated with authorities, while Telegram and X were more reluctant. However, all three stories share a key issue—perhaps the key issue: the ability to intervene in the content they host.
To understand the reason, let’s briefly recap what happened.
- Telegram, Meta, and X: Three Different Cases, One Common Origin.
Pavel Durov, founder of Telegram, was arrested in Paris on August 24th as part of an investigation that French authorities have been conducting for months against the messaging platform.
The accusations are numerous: money laundering, drug trafficking, child pornography, and refusal to cooperate with law enforcement. In the press release issued by the Prosecutor’s Office, there is even mention of violations related to the import and export of cryptographic tools—an approach reminiscent of the United States in the 1990s, when the government classified cryptography on par with weaponry. This interpretation only changed due to the outcome of the Crypto Wars.
In fact, reports tell us that Pavel Durov was released after a few days upon paying a €5 million bail, with the condition that he not leave France. Initially, Telegram issued a statement via Twitter, asserting its compliance with European laws. But on September 6th, the founder of Telegram decided to fight back, leaving little room for interpretation.
"Sometimes we can’t reach an agreement with regulators in certain countries on the right balance between privacy and security," Durov said, adding that, if necessary, Telegram will leave markets that are incompatible with these principles.
It is worth noting that this is not the first time Durov has clashed with authorities. In the past, he refused to cooperate with Russia by denying access to Telegram users’ personal data. This refusal led to the platform being temporarily blocked in Russia in 2018.
- Meta: Pressure from the White House and Zuckerberg’s Revelations
Mark Zuckerberg, CEO of Meta, recently disclosed pressures he received from the White House during the pandemic. In a letter to the U.S. House Judiciary Committee, Zuckerberg revealed that the Biden administration pushed Meta to remove content related to the virus, including satirical and critical posts.
Zuckerberg explained that in 2021, Meta deleted more than 20 million posts related to COVID-19 but expressed regret over some of the decisions made, admitting that the company had succumbed to excessive political pressure.
Zuckerberg emphasized that these requests were perceived by the company as an obligation rather than a choice, and in hindsight, some of these actions might have been mistakes. Meta’s future commitment, according to Zuckerberg, will be to better resist such pressures, even in emergency situations.
"I believe the government’s pressure was wrong, and I regret not being more transparent about it."
- X and the clash with the Brazilian Government
Elon Musk and X (formerly Twitter) are at the center of a legal dispute in Brazil, where the platform was blocked after Musk refused to appoint a local legal representative, as required by the country’s Supreme Court. The issue arose when Judge Alexandre de Moraes ordered X to suspend certain accounts accused of spreading political disinformation, particularly those associated with former president Jair Bolsonaro and his supporters.
Musk’s reaction was harsh. He accused the Supreme Court of corruption and of violating free speech, criticizing de Moraes and calling him a “criminal.” However, the judge continued his legal actions against Musk and his company, even freezing the bank accounts of Starlink, Musk’s satellite division, to pressure X into complying with Brazilian laws.
Brazilian authorities are even pursuing those who attempt to access the platform using VPNs, sparking further controversy over freedom in Brazil.
Currently, the platform remains suspended, with about 21 million Brazilian users cut off from the service. The legal dispute is ongoing and could have long-term repercussions for X’s presence in Brazil, one of the platform’s largest markets.
- The ownership of content
Telegram and X have found themselves in hot water for refusing to comply with content moderation mandates imposed by various jurisdictions. Meta, on the other hand, has avoided such issues by adhering to directives from the White House, including the removal of content flagged by Washington, such as “satirical and ironic” posts, as noted in the letter.
The decisive factor in all three cases is the same: the ability to intervene in what is published on the platform. The terms and conditions of Meta and X do not formally claim ownership of the content users post, but they clarify that users grant the companies a non-exclusive, royalty-free, worldwide license to use, distribute, modify, and display the content in relation to the services offered. Telegram’s terms are slightly stricter: while users also retain formal ownership of their content, Telegram requires a license to distribute and display content only within its ecosystem.
However, the result remains the same. Anything published by users can be modified by the platform, according to the implicit contract every single user agrees to when they begin using the service.
- Nostr is the way
It’s no coincidence that, in recent weeks, many who care about issues such as privacy and censorship resistance have reignited interest in Nostr. The protocol, whose acronym stands for Notes and Other Stuff Transmitted by Relays, can be used via various clients, not a single platform—similar to how the Web is accessible from different browsers.
But most importantly, users who create an account do not do so through a username and password saved on the company’s servers—because, in this case, the company doesn’t exist—but rather through a public key and a private key.
This key pair allows users to interact with Nostr across multiple clients and send their “notes”—as posts are called on Nostr—to as many relays (servers) as they wish. In other words, the data is not stored on a single server but on multiple servers chosen by the user—and the user can even set up their own server without much difficulty.
Most importantly, the data is portable. Posts sent are cryptographically signed: in Nostr, content ownership is not just formally with the user, it is mathematically so.
In such a context, blaming the operator of a client or relay for the content signed and published by users' private keys would be bordering on absurdity, besides revealing a clear technical ignorance. Of course, after the accusations from the U.S. Department of Justice against the developers of Samourai Wallet, it’s fair to be ready for anything.
But giving a chance to solutions like Nostr also means considering the possibility of reclaiming one's online identity and no longer being an unconscious victim of manipulative algorithms and invasive governments.

Three years ago, as the Bitcoin Law was coming into effect in El Salvador, I began my journey as a Bitcoin journalist. I started writing a newsletter in my native language, Italian, and called it 'Bitcoin Train.’ It’s a weekly newsletter that, starting from the latest news, delves into Bitcoin, its implications, and related topics.
I named it this way because Bitcoin is a long journey, filled with an almost infinite number of stops. From the initial orange pill to a deeper understanding of the world around us, to a radical shift in perspective, and passing through countless other stages along the way.
After just a few months, I realized that Bitcoin Train was gaining traction and could become something significant. I left my full-time job as a press officer, and within just over a year, the newsletter became my full-time occupation. Today, it is the largest Bitcoin-only newsletter in Italy.
Today, three years since its inception, I want to take it a step further. The events of the past few weeks have made me realize that Nostr could become a crucial technology for freedom of expression in the future, and as a journalist, I’ve decided to bet on it.
Starting today, I will publish the English version of my in-depth articles weekly here, on Nostr. I won’t rely on Substack, Beehiiv, Medium, or other platforms. The articles will be published here, openly.
Soon, I’ll publish an article dedicated to the importance of Nostr and its ties to the events of the past few weeks involving Telegram, Meta, and X.
The journey begins.

This.
In the past year and a half, many people have (rightfully) criticized NOSTR for its flaws, but the importance of NOSTR lies not so much in its features as in its very existence.
A protocol, however flawed, will always be better than alternatives that don’t yet exist. In recent weeks, many are realizing the need for a decentralized alternative.
Nostr is here. And that's all that matters.

“Journalism often functions as propaganda. The difference is that State propaganda at least openly acknowledges that it is propaganda. When a journalist publishes an article, people think it's journalism. I even see journalists defending the idea that journalism must have an agenda”.
The concept of agenda-setting is an aberrant one, yet it’s the first thing they teach you when you start studying journalism.
In these years, I’ve often criticized Bukele, but in this part of the interview published by Time, I must admit that he’s simply spot-on.https://m.primal.net/KUri.png https://m.primal.net/KUrj.png

THE DARK SIDE OF TELEGRAM FOUNDER’S ARREST
Beyond the mere reporting of events, the Durov case has obviously reignited the ongoing debate on freedom of speech and the power of authorities over social platforms.
The politicization of the case makes little sense—Durov has refused to collaborate with Russia in the past, not just with Western countries—so there are two key points to analyze:
- What should Telegram do for its customers?
- Who should decide the moderation policies?
Telegram markets and advertises itself as a privacy-focused messaging service - though it's important to acknowledge that there are other services that offer even more robust privacy protections.
Despite this, Telegram's positioning as a privacy-centric platform is a strategic choice that resonates with a large user base seeking a balance between usability and security. Given this brand identity, it makes perfect sense that Telegram would be resistant to collaborating with authorities on matters that could compromise user data. Such cooperation could undermine the very value proposition that has attracted millions of users to the platform.
If Telegram were to capitulate to demands for data sharing or content moderation in ways that violate user privacy, it would risk eroding the trust that underpins its entire business model.
Users who prioritize privacy might abandon the platform in favor of alternatives that offer stronger guarantees of confidentiality and security. Therefore, Telegram’s stance on non-cooperation with authorities is not merely a matter of principle but a strategic decision to protect its core offering.
Self-moderation is the only way.
A crucial aspect of the debate on moderation concerns the capacity and legitimacy of digital platforms to control content. When a company like Telegram introduces the possibility of moderating content, several fundamental questions arise.
First, in order to decide which content should be moderated, it is necessary to read all of it. This immediately raises privacy concerns: who guarantees that users' private messages are not intercepted? If someone can read messages, privacy is already compromised.
Secondly, who decides what is legitimate? The notion of legitimacy is fluid and varies from country to country, from government to government, and even within the same societies over time. What the European Union might consider acceptable today could be deemed illegitimate tomorrow, or vice versa. The same question applies to other global actors: which standard should prevail? Well, the answer is: those of the owner.
The only way to find common ground in this global context is not to rely on existing laws, which are often contradictory, but rather on the principle of private property.
Telegram itself should be the sole authority to decide what and how to moderate on its own platform. It will then be the market that judges its actions: users, through their choices, will determine whether Telegram’s moderation policies are fair or not.
If users believe Telegram manages moderation fairly and respectfully, they will continue using the service; otherwise, they will migrate to other platforms that better meet their needs.

If that were the case I would understand it, but I don't think it is. I see many bitcoiners posting memes and posts in support of Trump and the whole MAGA movement.

Bitcoin Magazine stands to #Bitcoin as the mainstream media stands to mainstream information.
Both represent reality in a distorted way and following logics of political interest far from the only interest that should matter: that of readers.
Until a few months ago, Bitcoin Magazine's line was clear: the “Bitcoin candidate” - literally defined as such - was Robert Kennedy Jr.
But then it was realized that Kennedy was going nowhere in the election. Especially when he withdrew from the Democratic primary to run as an independent presidential candidate next November.
Btc Inc. lobbying was then redirected to the favored candidate for eventual victory: Donald Trump. One who wrote in 2019, “I am not a fan of Bitcoin and other cryptocurrencies, which are not money and whose value is highly volatile and based on nothing.” Today he makes statements such as “Bitcoin mining could be our last line of defense against a CBDC.”
The result? Today in the United States the image of Bitcoin is associated with The Donald.
There is only one problem. Bitcoin is not compatible with Harris or Trump's values. Bitcoin is not compatible with the values of a political party. Bitcoin is not compatible with the values of representative democracy.
Bitcoin is an expression of the prevalence of the values of private property and individual freedom over all others. The rest is derived from pure logic. But this is too complex for the legacy media: which is why mass information is a cancer to be eradicated.

Maideira is definitely the place where I felt that #Bitcoin was perceived in the most *normal* way.
Without opening BTCMap once, simply wandering around Funchal, I found 5 places that accept bitcoin in just one day:
- 2 bars;
- 1 restaurant;
- 1 winery;
- 1 pharmacy.
I ended up buying sunscreen at the pharmacy, drinking a glass of red wine at the winery and having dinner in the city center, always paying in bitcoin.
The most impressive thing of all? In all three stores, when I asked to pay in bitcoin, everything seemed absolutely normal. No signs of panic, no signs of "damn I forgot how to do that," no signs of "I have to ask my boss." All the merchants took their POS and let me pay.
Bitcoin seemed normal not only to me, but also to normies outside our bubble. Congrats to @npub1etg…8n6e for their amazing job.

My 2 sats on Satoshi’s new emails.
The relationship between transaction fees and the economic sustainability of mining, as well as the connection between energy and the currency value, are aspects that Satoshi Nakamoto had carefully considered, as revealed by the largest archive of his writings ever published since he vanished from the public eye.
The Testimonies
The context is the British trial featuring the Crypto Open Patent Alliance (COPA) against Craig Wright, where the non-profit organization is attempting to prove in court that the Australian entrepreneur is not Satoshi Nakamoto.
Throughout the hearings, various testimonies have been presented for both sides, and, at the behest of COPA, Adam Back and Martti Malmi have also spoken. The former is the CEO of Blockstream and the inventor of Hashcash - the basis of Proof-of-Work -, the latter is a collaborator of Satoshi from when Bitcoin was taking its first steps, and also the only developer besides Satoshi to work on the second version of the Bitcoin software (Bitcoin 0.2).
In support of the testimonies, email correspondences between Satoshi and Adam Back as well as between Satoshi and Martti Malmi were released. From the six emails between Adam Back and Satoshi revealed in court - all sent between August 2008 and January 2009 - it emerges that the latter had contacted Back to ensure the correct citation of Hashcash in what would become the Bitcoin white paper. They also comment on B-money, one of the attempts to create a digital currency made by cypherpunk Wen Dai in 1998.
However, the most information is obtained from the entire history of conversations between Satoshi and his collaborator Martti Malmi, known also by the pseudonym Sirius. The latter has released over 250 pages of emails - available at this link - and below are the most significant parts.
Bitcoin according to Satoshi
Much of the most interesting content is reported in the first part of the mails, where Satoshi responds to the doubts Martti Malmi expresses about Bitcoin, in addition to giving him directions on the work to be carried out. This is May 2009, seven months after the publication of the white paper and just four months after the actual birth of Bitcoin.
The Fee Market
In writing, Satoshi does not distinguish between classic full-nodes and those that also mine, referring to miners also with the term nodes because at the time a simple laptop was enough to mine. Satoshi explains:
"I do not foresee transaction fees being necessary anytime soon, but if it becomes too burdensome to run a node, it will be possible to run a node that only processes transactions that include a fee. At the moment, such a node would not get anything, because no one includes a fee, but if a sufficient number of nodes did so, users would get a faster confirmation by including a fee. […] The transition, however, is not controlled by some person at the head of the system, but only by individuals reacting to market forces."
In short, Satoshi explains that if in 2009 the demand for block space was so low that transaction fees were not required - and managing a laptop for mining did not imply significant costs - the scenario could change in the future. And the change would not be dictated by "some person at the head of the system" - by a central authority - but by the simple reactions of the individuals involved to market dynamics.
Bitcoin as a Distributed Ledger
A reasoning easily linked to the fact that today Bitcoin is used not only for economic transactions but also as a distributed ledger for arbitrary files:
"Bitcoin is a distributed and secure server for transactions - writes Satoshi. A few lines of code can create a transaction with an additional hash of anything that needs a timestamp. I should add a command to timestamp a file in this way."
Then, if we think that criticisms related to the energy consumption of mining have only arrived in recent years, we are mistaken. Malmi himself tells Satoshi: "The last thing we need is to launch a system whose design involves the consumption of electricity and the emission of carbon dioxide."
“Unfortunately - explains Satoshi - Proof-of-Work is the only solution I have found to make peer-to-peer electronic cash work without a trusted third party. […] PoW is essential for coordinating the network and preventing double spending. If it were to grow to consume a lot of energy, I think it would still be less costly than conventional banking activity it would replace. The cost would be an order of magnitude lower compared to the billions in banking fees people pay for all those brick and mortar buildings, skyscrapers, and unsolicited credit card offers via mail.”
A relationship, that between Bitcoin and energy, which Satoshi had clear could represent the realization of what Henry Ford theorized in the '20s as "energy currency":
"The value of bitcoins - writes Satoshi - would be relative to the electricity consumed to produce them."
Explaining to Malmi the operation of the difficulty adjustment - addressed in this newsletter at stop #3 - Satoshi explains a concept as simple as it is fascinating that testifies to the independence of each individual node from all others. Trying to understand the mechanism of issuing new bitcoins at the time of approval of each new block, Malmi objects that, according to Moore's law, as more efficient hardware is developed, the supply of bitcoins risks increasing due to the increase in computing power available to people.
Satoshi, in introducing perhaps one of the most fascinating mechanisms of the entire protocol, writes very simply:
"Actually, this problem is handled."
There is a moving average that compensates for the total effort employed so that the total output is a constant. As computers become more powerful, the difficulty increases to compensate.
Malmi: "How is the difficulty of each block communicated across the network and how is it agreed upon?"
“It's not communicated. The formula is hard-coded into the program and every node performs the same calculation to know what difficulty is required for the next block. If someone were to deviate from the formula, their block would not be accepted by the majority." https://image.nostr.build/2cde7491ff5dac75faa5a0f431c556597c3bbdc097d1998064ceaf3981e29fbe.jpg

I contenuti espliciti sulla timechain ci sono da prima degli ordinals, che piaccia o meno è un sistema aperto e se si rispettano le regole del protocollo si può fare di tutto. Non ho scritto personalmente articoli sull’attacco statale perché può essere solo legale e, quindi, del tutto irrilevante. Sono abbastanza convinto che proveranno a bandire Bitcoin con o senza contenuti espliciti

Nell'articolo è spiegato. Molto probabilmente il destinatario non ha sufficiente liquidità in entrata/uno dei nodi intermedi non ha sufficiente liquidità da inoltrare. E' il principale problema del LN ad ora

Che succede quando si effettua un pagamento Lightning verso qualcuno con cui non si ha un canale? Avviene la magia del routing 🪄
La rete Lightning permette di raggiungere peer con cui non si hanno canali aperti direttamente instradando il pagamento tramite altri peer, a patto che esista un percorso in grado di collegare il mittente al destinatario.
Prima che un pagamento venga effettivamente eseguito, il nodo deve trovare il percorso da far seguire ai fondi: questo processo prende il nome di pathfinding. Oggi la rete Lightning conta oltre 16.000 nodi, connessi tra loro da quasi 43.000 canali con una liquidità media di 4.000.000 di sats.
L’algoritmo di pathfinding non ha difficoltà a trovare percorsi di pagamento. Il problema è verificare se i canali dei percorsi trovati abbiano la liquidità necessaria per supportare il pagamento.
Se il nodo A volesse pagare 1M di sats a Q - passando per B, K ed F - ma anche solo uno dei canali intermedi non fosse finanziato con tale liquidità, la transazione non avverrebbe.
Inoltre come si può essere certi che un nodo del percorso non si comporti in modo malevolo sottraendo i fondi? A questa domanda risponde il concetto di Hashed Timelock Contract (HTLC), uno smart-contract a tutti gli effetti.
