Everyone that's been censored on X should get together and file a class action lawsuit. X and Elon are in clear violation of the 'safe harbor' clause in Section 230 that legally indemnifies a site from content produced by 3rd parties. But Section 230 only allows for moderation of content in 'good faith' not editorialization of content which X and Elon are definitively engaging in. If X was found to be in violation of Section 230 it would be legally liable for all content on the site even if posted by a 3rd party.
