Freedom of Speech != Obligation to Listen
You’re free to be an ass and I’m free to call you one.
They know this because they people crying about the first amendment and “cancel culture” are consistently the ones doing it to others.
In the context of US constitutional law, yes. But freedom of speech can have a wider meaning in moral philosophy. What someone might mean when they speak of the idea will vary.
Anyway, I don’t think anyone has an obligation to listen to or host content they find offensive or harmful, but in the context of a public forum that hosts a wide range of non-curated content and discourse, removing content or banning people just because it is critical of you or you disagree with it may be morally wrong. Especially when there are clearly outlined rules and the content does not clearly violate those rules. This happens frequently on this instance (and others, but this seems to be the main offender among the big instances currently).
