Microsoft would not dream of sharing your extremely personal data with anybody else Of course there are understandable exceptions for terrorists, criminals. tax cheaters, illegal downloads in the boys room, speeding and shoplifting, and industrial espionage that clearly is in the best interest of the Nation.....

So if you have nothing to hide this is a dream. Obama has something to hide, the NSA has something to hide, the FBI has something to hide, your neighbour has something to hide....but you don't - right?
