It's still called censorship when it's against a social media company.
What interests me more is that Elon has completely reversed his anti-censorship stance. He was always censoring while opining against censorship and getting sued for millions of dollars for ignoring a Brazilian censorship law. Now he's just quietly complying with Brazilian censorship law.
I miss his feuds with the supreme court. Trump actually got the judges sanctioned under Magnitsky too, then dropped the sanctions not too long after. No clue if Elon helped with that.
