@feditips yes there is. You tell your friends on said platform you’re moving to a new one and they come along. On Fediverse let’s say Musk buys all the big ones. Can’t he then block any other ones from talking to his. So if I move off Musk’s owner popular fediverses onto a different one but he blocks alll that aren’t his won’t my friends who didn’t move off too be unable to see my messages?
