When someone claims "free speech infringement" and then has no data to back it up they are either trolling or don't really care enough to make a substantial argument.
Are you suggesting there isn't any banning? What precisely is your claim here?
BabylonBee is a recent example, and apparently Musk had a call with them prior to him making the free speech poll/twitter purchase: https://twitter.com/SethDillon/status/1511325246967660547 (Note: Musk has been on their podcast).
It is genuinely interesting to me. All of the uproar about “free speech” has been confusing to me. Who are these people being censored? What are they saying?
