I agree. Rav Kook, in fact, says on this in one of his letters “אי-אפשר לצמצם”. Some wanted to ban ספר יחזקאל and שיר השירים. In Europe מורה נבוחים was burned and all of the Ramchal’s books were put in cherem. Many other of our books were censored.
The question regarding social media is whether or not they are public forums. Courts have already decided (see, for example, Davison v. Loudoun County Board of Supervisors et al, E.D. Va. 2017) that public officials may not block people from their accounts for writing comments they don’t like. The big question is whether the managements of the media outlets can. Of course, Congress might be able to step and compel them under the Interstate Commerce clause or be bludgeoned by loss of immunity for posts as Ted Cruz has stated (see his essay “Facebook has been censoring or suppressing conservative speech for years” ).
