Really?
You do realize that what people are accusing the USA of doing (recording everyone's phone calls, copying everyone's emails, even storing their text messages forever and ever, and their skypes, etc) is what China actually DOES do--routinely? With no apologies? They block access to internet sites, too. China's goal is a world wide web that is controlled by governments, and they have said so.
Further, China has one of the largest "theft operations" going in the history of the world. The reason their drones look like ours is because they stole the plans. If we are building it, they are stealing it.
The reason you can buy discount Microsuck and other proprietary software in Beijing and Hong Kong is because they stole it and copied it. The reason they know what Australia's "NSA" building is going to look like is because they stole the blueprints. They have an entire military unit that has been up and running for years, whose business it is to hack, disable and steal shit--and not just from USA, not just from UK, not just from Australia, Israel, etc....from EVERYONE.
Two wrongs may not make a right, but there are no winners here, no heroes here, and no noble causes. The Chinese have been stealing for decades now; their theft of intellectual property is a big piece of their economic advancement.
I still think Snowden made a critical judgment error and he made it that much harder for the next clever non-high school grad to ever break into the national security game. I also would not be surprised if his hands are not as clean as people want to imagine.
