I don't think you understand Chinese culture or politics beyond the Cultural Revolution in the 60s. While the "communist" (though now they're just capitalists with an authoritarian flavor) party does engage in quite a bit of political and social repression, this is largely for economic reasons. China doesn't want people buying or selling western products because they want to keep most of that money in their own economy, not going to foreign companies. This applies to social networks and physical products. Despite the government saying the Great Firewall exists for cultural reasons, they mostly want to just keep the big business of social media in China. They aren't North Korea, they let people enjoy things, including western and Japanese media. Why else do you think so many blockbuster movies try to appeal to Chinese audiences?
