NO NO NO! SERN spies on innocent people as much as, if not more so than, the NSA. According to an insider named John Titor, they are currently trying to develop a time machine through Kerr black holes made through their Large Hadron Collider. This is kept hidden from the public, and all those who know more than they should will be targeted with their global scale eavesdropping.
Mostly marketing BS. No encryption M$ can deploy is going to protect your privacy from an agent with a "National Security Letter" or the inquiries of any other government whose jurisdiction they have servers within.

Even if these changes could have significant impact, governments would simply go after the services of whomever you are communicating with.
like Microsoft says its all cloud based your files are ''out there'' and not on your computer .. I have yet to understand why everyone just jumps on this bandwagon.. as my opinion I don't care to have my computers os cloud based as now with this and if your using 8 well that's its prime selling point.. you talk about the nsa but who else is tapping in to your stuff that's stored on o server somewhere in the world that don't have the laws to protect them from just anybody?? bottom line they talk it up about protecting your privacy but its the last thing they want to do cause then they cant target you so easy ..
