Yes overall but even then it's not so cut and dry. Think of, say, queer artists who depends on this to have a living, or minority activists who need it to be heard, to push back against the same hate spreading across it. If they simply up and leave before building up an audience elsewhere they'll just end up worse for it. For activists, even if they have other platforms, they still consider what will happen in the wider picture if a major platform like this is left to bigotry and toxicity unchallenged, and those who aren't bothered by it.

Sometimes taking the moral high ground is a luxury. Given the way some people criticize the irony of minorities who still rely on it, I don't think they really get how complicated the matter is.
