So I’m not sure that they’re doing a great job on that “only censor some of the unpopular opinions” thing.
They are in the sense that censoring an opinion strongly enough is one way to make it unpopular.
While it may occasionally happen that people justify their anti-ethical-value-of-free-speech behavior with “but my opponents did it first!”, if their opponents were very conscientious about the ethical value of free speech those people would probably just decide that the ethical value of free speech was an Enemy Thing and people who support it are evil.
You seem to be unclear about how iterated prisoners’ dilemma works.
