Civil rights groups like the Electronic Frontier Foundation have been documenting the impact of these revelations on civil rights. They have a post on their site on 22 documented cases on the impact of the NSA spying on the right to association. You can be sure, the EFF didn't have to dig that hard to find them either.
And it's not just people worried about civil liberties; the Internet companies that had their security compromised are upset too. In fact, according to an article on Forbes.com, the country's biggest tech companies, including Apple, Microsoft, Google, Yahoo, Facebook and AOL, sent letters to the House and Senate Judiciary committees demanding some reform.
