>Besides obscene and illegal content, it is not allowed, as this article lists, to post “politically sensitive information”, “spread rumors,” “bring news about Hong Kong, Macau or Taiwan that has not been reported by official news channels,” or to publish “military information.”

The scope of "illegal activities" is what's at fault here, not the means by which they are enforced.

The fact that we can even have this discussion is in itself proof that there's orders of magnitudes of difference in allowed speech.
