remember that Microsoft built a freakin' backdoor into Outlook.com for the NSA, with Microsoft working for months to provide the NSA with full access to encrypted chats on Outlook.com, something we reported about in July 2013. Microsoft also worked with the NSA on giving them a backdoor into SkyDrive, their cloud-based storage service. At the time, I reported: "Microsoft worked tightly with the NSA in order to give them access, with the NSA reporting on April 8 of this year that the Redmond-based slave of the NSA built PRISM access into SkyDrive that removes the need for the NSA analysts to request permission to search SkyDrive".
Oh, and Microsoft also gave the NSA access to Skype. In my article from July 2013, I reported: "Work on this began back in November of 2010 with data collection a few months later in February of 2011, with the NSA document stating that the planned systems worked well, with full metadata collection enabled. The NSA thanked Microsoft for their help, saying that "collaborative teamwork was the key to the successful addition of another provider to the Prism system".
