It doesn't matter. The main problem here is not hacking. It is piracy as the Chinese government stole their software.
I wonder what would happen if Anonymous decided to target China over matter like this. Sure would be impossible to bring a government like that to their knees. But at least the public would gain some awareness on this matter.
Before you grabbed that little war drum, if you thought of the consequences you really wouldn't want to start such a conflict in the first place.
The quick, unorganized retaliatory response from an anonymous actor is usually such that it puts innocent services and people directly into the crossfire. Not to mention an anonymous moniker allows anyone to act on the behalf of anyone.
Who said it has to be quick and unorganized? While officially the US can't 'engage' China in this way, another NGO could start and perform long term campaigns against Chinese corporations and assets similar to what is detailed in this article. I'm also not naive enough to think that this hasn't already begun.
It doesn't work that way. If the U.S. government condones cybercrime, it cannot allow an NGO to engage in it towards a country that you have diplomatic relations with. I agree with "Kill that noise right now" comment above.
