There are lots of such people on social media, if you know where to look. The trick is that none of them are directly calling for arrest for what people say. Instead they masquerade that under an accusation that attacks your person, e.g. they accuse you of harassment, of spreading propaganda, or of some crime. With the goal of silencing your views — all without ever engaging with the arguments that you provide. This is especially noticeable if you look at topics that are non-mainstream-acceptable.
So you call silencing tactics a form of freedom of speech as long as it's not by the government? I find this a really shortsighted way of looking at freedom.
According to the original Enlightenment ideals, during which the idea of freedom of speech was created, freedom of speech is valuable not because it is inherently so, but because it's supposed to improve society. It creates a Marketplace of Ideas, and through rational debate, the best idea wins. During the French Revolution, Liberté was supposed to be equally important as Egalité and Fraternité, i.e. societal responsibility mattered just as much as freedom.
What is the point if freedom of speech is used to destroy the Marketplace, and if freedom of speech devolves into a form where everybody shouts but nobody listens to each other (i.e. the post-truth society)? What is the point of shouting on an island, instead of reconciling differences?
