Well there's always the classic "Exit, voice and loyalty", which works whether we're talking about corporations or governments.... One thing that irks me sometimes about general "libertarian" discourse is how much they (we?) seem to be invested in defending the status quo of Giant Megacorporations, especially in the social media space, because they're trying to stand up the other side of the argument from overzealous regulators like we saw in the Biden admin. It's like dude, Elon Musk isn't the "Howard Roark"-ian figure you're projecting onto him. There he was, lined up behind Il Duce with all the other moguls at the inauguration. I get that "exit" can be tough when it comes to providers of physical things like Amazon, etc. But it should be easier to Kill your Twitter than it seems to be for most people.
