The biggest problem with federation is easily visible in e-mail: the server “owns” your address and therefore moving in very hard. It’s not much better than any other silo in that way. Mastodon is a bunch of small social sites in a trenchcoat.
There are ways to make identity floating and separate from the server, at least in theory, but ActivityPub (the protocol under Mastodon and many other things) does not implement anything like this.
