It makes no difference if the person controlling it is a billionaire good guy or bad guy. The result is the same. If you go down the route of mastodon then all you’re doing is segregation.
In scenario A you pool people together into 1 big void and everyone gets angry and both sides consider each other wrong.
In scenario B you segregate people into groups of opinions where the moment your opinion differs you’re kicked from that group.
Either way we are long past the time when you could have an educated conversation and debate.
I have no desire to join a void with single opinions and nothing to discuss.
The whole point of federated activitypub servers is the opposite of segregation - everyone gets to use whatever server they want and they can still interact with anyone else. Servers blacklisting each other (or defederating) is possible of course, but nothing's stopping you from just joining another server, and twitter at this point is just a large defederated mastodon instance anyway.
Server black listing can be copied so servers can get blocked before they are even listed. If an admin doesn’t like you and you get banned then you have to rebuild your social circle. You could host your own but really who wants to do that?
