I don't think the government has the power to ban twitter, and it probably shouldn't. But individual users should stop using it.
Unfortunately, people are emotional little bags of shit and just want to see their funny memes.
This is why we can't have nice things. Too many people are basically toddlers and cannot delay gratification.
On the other hand, the government probably could have Musk killed. That's kind of scary and I don't really want to have a government that would do that, but do I want that asshole to die.
I am reminded of that old post about the guy who was into poop stuff, and hired a sex worker to do poop stuff on him, and then right when it actually began he realized the reality was absolutely not fun. So that's a possibility for you. But maybe you'll enjoy it! Be safe have fun.
