First, if you're really worried about privacy, why is it not a DEFCON 1 outrage that state DMVs are selling your info to private investigators? [1] Or if you're really worried about your personal liberty, isn't your local police force a greater threat then NSA eavesdroppers?
Back in 2013 the NSA claimed it was spying on 29 petabytes of internet data (out of 1826) a day [2], or 1.6%. That's both a trivial amount of overall traffic and an insanely large dataset at the same time (since it accumulates every day).
Isn't a big chunk of that traffic encrypted? Even if it's not, how do you find terrorists in that data? Do they self-identify? Even if they use a trivial substitution cipher ('cupcakes' instead of 'bombs') it would evade these billion-dollar supercomputers.
To me the NSA's spying program was security theater akin to airport security: expensive machines that don't even catch terrorists. They fail their own internal tests 95% of the time! [3]. I personally would like to know what algorithms the NSA was using to successfully identify terrorist data in exobytes of (possibly encrypted) datasets. Sounds like billions spent on airport scanners to me.
Finally, on a political level, Snowden seems like a massive hypocrite to me for hiding in China, which harvests the organs of political prisoners [4] and Russia, which routinely assassinates political opponents and journalists [5]. But he's mad that what, the US was reading his Gmail?
I realize he's super popular among the HN crowd and the libertarians for whom all gov't surveillance is evil but I, for one, am not a Snowden admirer. Downvote away.
