You realize that many have pointed out that the Guardian's stance on this has some serious factual errors right? And when told about these errors they've been very slow to correct them. For example neither MS or Google allowed the NSA "direct access" to their servers, they use sftp. Additionally Yahoo has nothing to loose at this point, the company is still in a tailspin, MS, Google, and Facebook have lots to loose if they attempt to square off with the NSA.
