To many, federation is a solution to a problem that doesn't really exist for them. In their mind, the early model of federation is like email, a problem that was "solved" years ago by having one corporate product that was much better than others (Gmail).

To add, on top of that, the fediverse is like if gmail could just randomly decide to stop receiving emails from outlook addresses and there's nothing any user can do about it except make another email for when they want to email outlook users.

I don't think fediverse proponents know just how catastrophically this terminates their entire pitch in the minds of 99% of internet users
