Nevertheless, the Guardian goes on to report a timeline of when the tech industry's giants came to be involved with PRISM:

"Some of the world's largest internet brands are claimed to be part of the information-sharing program since its introduction in 2007. Microsoft -– which is currently running an advertising campaign with the slogan "Your privacy is our priority" -– was the first, with collection beginning in December 2007."

So don't believe them when they say this (from IGN):

Microsoft stresses that "you are in control of what Kinect can see and hear. By design, you will determine how responsive and personalized your Xbox One is to you and your family during setup. The system will navigate you through key privacy options, like automatic or manual sign in, privacy settings, and clear notifications about how data is used. When Xbox One is on and you’re simply having a conversation in your living room, your conversation is not being recorded or uploaded."

Players will also control whether Kinect is on, off or paused. "If you don’t want the Kinect sensor on while playing games or enjoying your entertainment, you can pause Kinect. To turn off your Xbox One, just say 'Xbox Off.' When the system is off, it’s only listening for the single voice command -- 'Xbox On,' and you can even turn that feature off too. Some apps and games may require Kinect functionality to operate, so you’ll need to turn it back on for these experiences."

Your personal data will never be available to anyone outside of your console, Microsoft stressed. "You can play games or enjoy applications that use data, such as videos, photos, facial expressions, heart rate and more, but this data will not leave your Xbox One without your explicit permission."
