There’s no right to be heard, true. Yet, these are users complying with TOS. Beyond that, do the users have any obligation to not spread content that they haven’t validated? It seems an unreasonable burden to place on users who don’t post content for consumption by folks who care about such things. Can you blame people for speaking their mind and playing to their audience? Maintaining the platform and only posting constructive, mainstream content only appeals to a certain kind of person, and they may never reach their intended audience with such messaging, warping and contorting their content into something else entirely, potentially alienating the very people they are trying to reach in the first place.
I’m a descriptivist in the linguistic sense, and when it comes to free speech. More is better. Full stop.
I remember when everything was hard online. I don’t wish for those days to return, especially just to comply with misguided, ineffective government mandates at the behest of megacorps and special interest lobby groups.
I do have a breaking point, as far as ideas and speech; I believe that some ideas are stalking horses for violence, and the people who spout them have no goodwill. Some ideas can't be reasoned with. I'm glad I live in a country that still allows people to speak those ideas, but very few people will defend that notion anymore. I'll defend their right to speak those ideas. I just don't think a private company should be immune from the result of providing them a platform.
The right to free speech should be absolute. But there's no right to be heard. Somewhere along the line, people seem to have misconstrued that, because social media made it so easy to be heard that people assumed that was the definition of free speech.
