I’m going to go against the grain here and say that there’s a lot of gatekeeping and shaming going on, especially against the Mastodon owners who are thinking about federating with Meta’s instance.
Federating with Meta’s servers should be a choice. If people want the ability to interact with celebrities and normies, that would be a huge boost to ActivityPub and Mastodon in general, especially for the servers that do end up federating with Meta. Their users would be able to interact and follow all of the mainstream people who are not on Mastodon.
It should be always be a choice. And for those servers that don’t federate, things will remain the same. Don’t try to gatekeep or spread FUD, it just makes you look paranoid and insular.
