It's really interesting that such a bland, un-subversive show whose only mentions of sensitive topics are in bad throwaway jokes is so heavily censored. I guess a more interesting show would just not get aired at all.
Some of these jokes which are censored for criticism of China are so tasteless that they ought to be censored in the American version as well, or better still, never written at all. A joke about whether the "chicken" at the local Chinese takeout restaurant is actually chicken? In the 21st century? That is supposed to be amusing?
I think it's important to distinguish between government censorship and corporate self-censorship. Almost nothing should be censored by the government. Almost anything can be censored by private parties (however cowardly such censorship may often be).
Government censorship can look at lot like corporate censorship, remember Zuckerberg said Facebook limited the reach of the news story because FBI informed them something. I am sure this is probably not the first time American government “requested” a corporation to censor something without the public knowing.
