>Unhappy with your social network, say because there are too many Nazis and conspiracy theorists running rampant? Bad luck, no federation requirement means you'll lose all your followers and they'll lose you.
I don't know how a government would enforce this. Nor if we want them to. Yes, you will and arguably should lose your followers if you move sites, and that's because your followers are passive browsers who don't care about you specifically. None of us are Taylor Swift who will have millions follow wherever she decides to go. That's one offset of anonymity in this case.
Also kind of funny that you mention federation as an implciit solution and then complain about email.
> Unhappy with your phone or PC operating system? Good luck, in the best case you just have to buy all your applications again (if they are even available at the competitor), in the worst you'll have to live with frankly sub-par open source alternatives.
Again, yes that makes sense. you acknoledging that they have better OS's seems to be submitting that there's value in their service. Personally, I can replicate 99% of what I use on Linux and a de-Googled AOSP, but it will vary from user to user (RIP to the artists stuck in the Adobe suite). Having a better service isn't grounds for a monopoly alone, that's just plain ol' competition.
