You are literally, right now, looking at a “press” capable of instantly delivering content worldwide to billions of potential readers. Nothing is stopping you but your own resolvable ignorance. Nobody is censoring your content published on your own press. Nobody is stopping a willing audience. Getting that audience to request your content, well, that’s your problem.
It's not a press. It does not write columns meant for publication. It controls what other people say to each other. It is a telephone system, not a newspaper.
It is also a deadly threat to freedom if it is allowed to control public speech.
