Earlier quoted context omitted.
If you want to keep your followers you'd need to migrate before they ban you. But yes, I guess you can start over somewhere else while on big ones you're out forever. So in that sense I guess it is a tiny improvement. But if most of your followers were concentrated on server[s] that don't like you, you may not be able to reach them anymore.
If your followers are "real" followers, and if you are important to them, they'll get in touch outside the fed and will know where to find you. Maybe that's what we should strive for. I have 200+ followers on Twitter, but if you ask me, I can only name 15 with real, social interaction. And I think that's great.
I had over 10 thousand and had many interactions with people but wouldn't feel like bothering them on other platforms (unless it was of the same nature).
And the few people who bothered to contact me personally felt a little awkward too. I don't necessarily want to be talking to these people directly.
The magic is you just publish whatever you want and people can look at it. They can comment but there's no obligation to respond. Having actual conversations with that many people would be a huge chore. The whole thing isn't about having relationships with people at all but about spreading information. It could be about yourself in which case there would be some implicit one way relationship but that's just one use case.
