This is absolutely true, but it doesnt seem to be in line with the 'whistleblower' image that has been projected so far, and more in line with plain espionage.

It appears to my jaded eye that Snowden copied everything possible while in the NSA, revealed a certain amount to rile up the public opinion in his favor and to cover over the fact he was copying everything in sight.

He seems to be positioning himself as a literal espionage agent right now, giving operational secrets or at least implying he is willing to reveal operational secrets for special treatment from china... and no doubt money.

The tone of his statements seem to be like a chinese propaganda mouth peice right now... funny how things are never as simple as they look at first glance
