I find the Open Letter that was publicized by [AOL, Apple, Facebook, Google, LinkedIn, Microsoft, Twitter, Yahoo] to be supremely ironic, calling for specific limits on the governments ability to collect, hold and use data on individuals. While they insure their own access is unfettered and as secretive as possible. The US has quite weak protections in place for personal data: legislation is ‘controlled’ as per everything else in Washington by the collusion of ‘power-full interests’.
For one strong alternative voice in this instance, check out Eben Moglen’s series of lectures “Snowden and The Future.”
