It sounds to me like the implication here is --Snowden disrupted our intelligence agencies by preventing us from crucial information, therefore he harmed our government--. The assumption being that America and it's allies are entitled to all the information we are stealing through spying. When a non-American ally spies on America it's a crime, but when America spies, stopping it is a crime?
It's worth considering the idea that technological spying by procuring vulnerabilities without reporting perpetuates a technological arms race and concentrates power in the executive with no balance among other branches.
