If Snowden revealed anything it's that there is lots of hypocrisy involved and for the most part American citizens are in line with that hypocrisy as long as it does not effect them personally. And if we see China's behavior it's in line with accounting for this hypocrisy. Sure the US calls them out on it all the time, and they can't respond to the allegations... But similarly their citizens are on board with their hypocrisy. It's a world full of liars looking to exploit however they can so they can get to the top and remain there. It's all propped up on a commonly accepted fiction, if you did a bit deeper you see all the fictions are there to support various power structures and keep them functioning.

So can you blame China or the US... Not really everyone is playing the hand they were dealt the best way they know how.
