There is no way they wanted people to know about prism etc. No way. They're spooks. Spooks keep shit secret. That's an important thing. Why would they let the cat out of the bag for a such a spurious project? Even if they do have bigger stuff that we don't know anything about, which they most likely do, it's still a chump move to let everyone know about stuff as big as this. Once everyone starts tightening their shit up, it hurts their ability to do what they like doing and is their number one reason to exist, which is spying on people. The loss is bigger than the gain.
Sorry, I just don't buy it. Trying to find a shitty conspiracy behind an actual major shit's going down sort of conspiracy just seems a touch excessive.
It is actually not the purview of the NSA to do PSYOPs like thisbut it is the purview of the CIA, and Snowden has CIA connections. And it is not always as clear cut as taking actions which clearly serve a clear agenda. Quite the contrary. Black ops usually have the appearance of originating from a hostile actor.
Revolutionaries are not the only ones who have studied Hegel.
Ok, I'll bite.

So.. let's play this out. Snowden was leaking about NSA on behalf of the CIA. CIA want to achieve some sort of real effect in the world via this, through setting up a dialectical response from the world at large.
I'm trying to follow this through, but you might need to hold my hand through it. What is this effect and why do the CIA want it? People tighten up their security? Which people? Corporates? Why does the CIA care?
Create a feeling of paranoia and insecurity? Which dialectically does what? One would think it would make people more, rather than less, likely to resist? Aaaaaand...... that's what they want? So they get more powers?
It's a bold argument. I like it. Still not sure I agree though.

Also, probably worth saying, not sure if any revolutionaries are still into Hegel. (Zizek doesn't count). I thought it was more about Deleuze these days. You could be right though, what with the state = manifestation of universal spirit thing, CIA dudes with the time for reading philosophy probably would get a hard on for him. It's a funny thing to contemplate.
