If someone commits suicide because of online words from a stranger then they were not mentally well in the first place, and maybe shouldn’t be online at all but rather getting help. Doxxing is not quite free speech? It’s an action taken against an individual. Free speech for example doesn’t grant people the ability to accuse you of crimes Willy nilly, if they do so they are liable for defamation.

But that’s neither here nor there, platforms as private spaces have a right to limit free speech as much as they want. I don’t think it’s good for society when they use that power too strictly, and the fact that they did for about a decade I think it’s one of the main causes of the rise of the alt right, but it’s a right the platforms have. Just like you can kick someone out of your house for saying something you don’t like. When one says free speech what is meant is that someone in a public space can say whatever they want, be it hateful or not.
