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.
