That precedent kinda already existed. It already happened to a much larger degree with Tumblr and even fucking OnlyFans - a site whose sole purpose is sexual content.
Leave itch if you want, since I won't blame you for this leaving a fairly nasty taste in your mouth, but the same problem of payment processors getting to suppress whatever they don't like will keep occurring elsewhere until something is actually done about it. And companies ain't gonna do that, because they either can't afford it or just have no interest in dealing with it.
