1) Twitter is a private business, your first amendment rights have not been violated. A single company having everyone's "official" communications by the balls is a direct result of everybody literally handing them that power.
2) Can't be censored on your own equipment. Twitter is trash. Leave it.
Again... Twitter isn't.... A democracy. Democratize your social media, then it will function like you expect it to.
Twitter ain't a utility.
The President cannot block people because he is President. This would be the case on any platform.
And they are btw, one thousand percent hosed the moment he leaves their platform. They're only afloat because they get free advertising every hour of every day because the president uses their service.
Once he's no longer in office, they got a tough choice to make. If he's no longer a public official, there's no reason to keep otherwise ToS breaking tweets around.
A silly domain for test deploys, now has a mastodon instance. A place for memes as shitty as the name. Zero bullshit tolerated.
