The reason Mastodon and the Fediverse is spread out on so many servers is it protects it from being taken over by anyone. Not even the richest can buy this place.

Centralised services like Twitter are incredibly easy to buy out. If you move from Twitter to another centralised service, sooner or later that will get bought out too.

The point of the Fediverse is to break this buyout cycle, to let people be permanently in control of their accounts. More info here:

@feditips Ok, so what happens if one of those servers is unable to pay their bill and goes under. What would happen to our profiles, posts and follows? Would we have to start over on another server? From scratch?
@therealduckie @feditips Yes, but servers agreeing to the mastodon server covenant are supposed to give users 3 months notice before a shutdown. https://joinmastodon.org/covenant
