Plus, even Twitter was used to censor opponents of Biden, it's in Twittergate.
No, they didn't. They did not censor "opponents" of President Biden in any way, shape, or form. The ONLY thing that was done was the government suggested, not demaded, Twitter/Facbook/et al take a look at all the harmful and outright falsehoods being pedaled which could potentially lead to people's deaths.
If you want to talk about real censorship, look at how many times "free speech" Musty has banned journalists accounts after they posted mean things about him, or the multitude of problems with his vehicles, or the guy who said Musk should pay more in taxes and his account banned for days, or the current broo ha ha over any account which mentions Hans Kristian Graebener being StoneToss being banned. That's real censorship, but because it's done by the failing company, that's fine, right?
