None of these articles about this say the source of this information was Snowden. It also doesn't seem to be his M.O. to leak about non-privacy invading bits. Like nothing here really pushes any buttons for me other than it was leaked. A separate leak?
Agree this goes against the Snowden trend. Probably not him.
But since they're claiming to hack the Chinese, Russians, Saudis, and Pakistanis, this very well could be an "authorized leak" to counter the Snowden leaks. Like, the NSA actually does go after their enemies (as well as their friends). Very few Americans would oppose to them hacking Chinese Army computers.
The Al Jazeera English article that sparked this thread was summarizing yesterday's New York Times article, which mentioned Edward Snowden's name five times.
