Literally , 10s of thousands of accounts associated with customers of Microsoft, Google, Facebook and Yahoo are being REGULARLY turned over to US government authorities EVERY six months as the result of secret court orders. This has nothing to do with terrorism – it is all about taxes. There were only 19 people alleged to be the terrorists in 911. Not 10s of thousands. The big four are under a lot of pressure for any terrorist now knows what they do and would never use any of these systems. The only people are those who do not realize this is all a hunt for taxes – not terrorists.
