What are the forces pushing in the opposite direction? If you look at what happened to Erika Christakis or Bret Weinstein (try to ignore everything that Weinstein has become since then) it's hard to say that academia is not more highly policed than previously. Of course in some ways this is good, in that I recall some professors mercilessly ridiculing some students in front of the whole class, and of course professors having sex with some students which was always terrible but had no consequences until a few years ago.
