O'Sullivan's Law is why it seems like those platforms are left. Dorsey and Zuck aren't left, they are simply using the leftist useful idiots to grow their power. The left wants communism, the Jack and Zuck want techno-feudalism as communism would destroy their wealth and power. It's a dangerous game and the elites underestimate the toxicity of Marxist ideology.

Those platforms were originally created at a time when free speech was a given, once they have enough power, they can begin to enforce control.

If the right attempts to build an escape platform now, it's crushed by big tech, Apple and Google banning the app, their cloud provider likely to fold next.
