There's actually quite a bit of public outrage over the NSA revelations, but the people who benefit from this spying are spending a lot of money to suppress the story in the media and to astroturf social networks to make it seem like all the reasonable people are perfectly OK with their own government spying on them.
If you think I'm wrong, start paying closer attention when the story about NSA spying comes up on websites and blogs. Read the comments about how you should "Stop being such a drama queen about it, because privacy is so 20th century" and notice the similarity in the form of these comments.
I'm not saying they're made by the same people or even by an organized campaign (not necessarily anyway), but I'm saying that a lot of the "opinion makers" are worried, and that's the real story here. They're worried enough to either decide just to not talk about it too much or save their own bacon by coming out in favor of NSA overreach. It goes something like this: "Yes, mistakes were made, but the issues are being addressed" or, "There's overreach, but at least we're safe" or "The people who have exposed this overreach are a bunch of attention whores" or, "Get over it, princess. Privacy is a thing of the past because you use Google". Don't ask me to explain the rationale of that last one. I guess somehow, if you decide to have a private transaction with a private party and you give them your name and phone number, I guess it means that it's OK to do a pen register on your phone or put your contacts list into some database of some private contractor working for the government (and working for other private companies).
People see what happens if you rock this boat too hard. People are tacitly aware of what can happen if a little birdy drops a word in someone's ear about you. There are names in the news of people that nobody really wants to mention too much, like Aaron Schwarz and that Rolling Stone journalist with the car accident or even just Glenn Greenwald's partner getting hassled in a UK airport. For 9 hours. Nobody needs that. Ain't nobody got time to fight a faceless contractor who works for a company without customers and without accountability who works for the Federal Government. Hell, I don't even have time to fight with my phone company, and I'm gonna take on who knows who?
If your credit rating goes bad, you could lose your job. If the FBI start talking to your neighbors, you could lose your apartment. If you're so much as questioned, it could change the way people look at you. In an environment where jobs are scarce and things uncertain, it's not hard to put enough fear into people that they'll just decide to keep their heads down and pay attention to their fantasy football league instead of expressing their outrage that now our government treats us all like the enemy.
