Earlier quoted context omitted.
The thing is, the Chinese are fiercely nationalistic - it would not surprise me at all if many of these attacks are being done without government sanction. I would tread carefully on news like this - it's easy to read too much into it, and it's too easy to manipulate, kind of like blaming all communists because one of them set fire to a building.
Are you kidding me? Take a look at this video http://www.youtube.com/watch?v=Q_gSasJPs1Y . Chinese Plain-Clothes Officials Block CNN Cameras With Umbrellas In Tienanmen Square. How low can the Chinese government goes? They operated like a gang, no less.
Nobody is saying the Chinese government isn't censor-happy and oppressive, but get a grip on yourself man. Talk to some Chinese - particularly the young ones - and you will find a population very truly eager to attack the West in whatever way they can. It's more than likely that a significant number of hacks coming out of China today are occurring out of people's own free will, not by the explicit order of the government.
