The idea that Microsoft would be "privacy-guarding" is completely laughable to me, when they have so much poorer security than even Google right now, and Google already has major privacy issues on its own. Microsoft would be one of the last company to trust with my privacy. At least when Google says they aren't giving direct access to their servers to the governments I somewhat believe them, but I wouldn't believe Microsoft at all if they said that to me. They've had too many Skype privacy blunders to trust them on this.
