You're getting a lot of flack for this comment, but I think it's a reasonable way of looking at the problem. In the United States, we have strong cultural conceptions about what are acceptable reasons for the government and companies to forcably suppress information (copyright violations, "terrorist" content, white supremacy, child pornography) and what aren't (political dissidence, social stability, insults, most other porn). Culturally, the Chinese have about the same attitude towards political dissidence that we have towards terrorist recruiting content, and for many of the same reasons. Historically, they have seen how political turmoil, if allowed to recruit, can hurt and kill people just how we have seen that terrorism can do the same.

Similarly, the American attitude towards copyright, trademark, and patent laws probably seems ridiculous and borderline unethical to Chinese companies looking to do business here. They seem (from the outside) to have no problem with a phone manufacturer calling itself "Applle" to piggyback on Apple's brand, but that is very illegal under American laws. Similarly, the amount of automatic filtering YouTube and other video hosts have to do under DMCA might block as much content as Chinese political auto-filtering does, although I would love to see more analysis of that.

Being from an American cultural background myself, I have an obvious set of intuitions about which of these are reasonable and which are ridiculous, but I find it hard to make a clear argument about why.
