Re: "Open source is almost the perfect embodiment of communism"
Communism isn't a religion, its a political and economic philosophy. It does share one trait with religion in that its founders and early adherents were driven by idealism, "the brotherhood of man" sort of thing, but that idealism gets rapidly tempered by practical experience. (We hope.)
The Chinese have always demonstrated this practical streak, starting in the 1920s when Chinese communists split from Russian communists because the Russian ideology built around the primacy of the industrial proletariat wasn't suitable to the Chinese experience or culture.
The danger that communism presents to us, "the West", isn't that its some kind of nefarious war-like cult bent on World Domination but rather that its inherently more efficient and productive than our economic system. This might sound a bit odd given the failure of central planning in the USSR but that was once again a consequence of idealism -- early communists were enthusiastic adopters of scientific management ("Taylorism"), or as we know it today "the tyranny of the spreadsheet".
Incidentally, don't just assume Chinese people can't write code. I've worked with far too many of them that are very competent programmers and engineers. (....and there are a lot of them.....)
