Microsoft said in a statement on Thursday that it only gave up customer data when it was done through government requests." To be clear, Microsoft does not provide any government with blanket or direct access to SkyDrive, Outlook. com, Skype or any Microsoft product, " the company said." There are aspects of this debate that we wish we were able to discuss more freely. That’s why we’ve argued for additional transparency that would help everyone understand and debate these important issues.
