But this one is important, no? This is like banning Firefox because it can connect to illegal content.

Yea, it's a lot like that. The idea of banning browsers that don't actively police what users are able to access (maybe via something like a global blacklist) is no longer crazy.

It is relevant, it makes it more absurd than Parler's bans but, I was just trying to point out they're for the same core reason.
