Cordn is 100% decentralized.
Every chat room in cordn has it's own coordinator, every coordinator has it's own set of relays you can contact it on. I have 4 different coordinators, across 17 chats.
Some with more than 40 members, others with less, some with bots doing their own things. I run my own coordinator and I use other's coordinators. I can invite anyone in any of these chat rooms between any of these other chatrooms on any coordinators. I can even automate this with welcome agents, or etc.
In a way, this is "Highly Available" MLS, and to completely put the nail in the coffin of the fud you are spreading here, eventually the UI will make it even easier to switch between different coordinators if they are offline or moved.
That sucks if people don't pay attention. Looks like some FAQ could help, I dunno.
