Twitter however did not act alone. The tech giants conspired together to mass censor speech they politically disagree with in the 2020 presidential election. It's not a conspiracy theory, it's not secret in any regard, they were openly and directly sharing block lists with eachother and acting against only the political party they consider their adversary (rather than equitably enforcing their terms of service, behavior that has been going on for years now).
Their executives should be in prison for that level of criminal collusion toward election interference given their extreme collective monopoly status. Merely breaking the companies into pieces is not enough.
There's absolutely no reason to allow Twitter to censor, because it's become the modern version of the telephone system, and the world is relying on Twitter in today's world in an even more important way than telephone texting.
The only people arguing in favor of censorship right now are the Democrats, and it's SOLELY because Silicon Valley is reliably left leaning, and will only censor Republicans.
