I had started to do a Twitter thread on all the news on suspensions of Trump's social media accounts and the removals of Parler, but instead I did a piece on these issues and the misunderstandings that seem to have accompanied them https://www.americanactionforum.org/insight/no-big-tech-did-not-violate-the-first-amendment/

First, Twitter and other social media platforms are private actors. They have not been found to be the "public square" by the courts and banning users is not a First Amendment violation.

Second, no revoking #Section230 would not have meant that platforms couldn't do this. Additionally, revoking Section 230 would place a greater liability burden on platforms.

Revoking #Section230 would mean more removals not only of the content in question but also for other speech that may touch sensitive topics. For example the Me Too movement would be difficult to carry if platforms were worried about defamation lawsuits.

Finally, no the fact that several large platforms acted against Parler around the same time is not evidence of collusion or a conspiracy or a monopoly. It's also important to remember there is far more to the Internet than just "Big Tech"
