>"When did we switch from capitalism to socialism? You own their infra and agency now?"

This is a non-sequitur. Organizations censoring speech can happen under any kind of economic system.

As a thought experiment, how would you react if Amazon, Google, and Microsoft, collectively decided that Libertarians were a problematic and dangerous threat? And, these companies decided to de-platform every libertarian account they detected in the name of public safety. Would you champion such behavior? Would principles dictate that you defend their right to suppress you? I know this seems like a bizarre thought experiment, but I genuinely think the Libertarian crowd gladly defends their own censorship.

Ultimately, which do you value more, Capitalism or Liberty?
