There are a lot of ideologically aligned people on Mastodon that left Twitter for a good reason. Showing them a better alternative would be great. I want people to have choice. If a subset of those users want to create their own relays and socialist them up - let them.
Outside of that, most of the infosec community moved there and I like to have access to that info as it’s relevant to my work so that’s a very practical issue for me. I’d rather have the problem of having to curate than not having the data available where I want it.
