I’m going to say it from the start: be aware that nothing is confirmed as of now. Apparently, The Guardian claims to have “top-secret documents” which reveals that Microsoft has feed NSA with private information like access to outlook emails, Skype Video calls and Skydrive over the past three years.
So, I might ask, how Microsoft was assuring us that an always-on Kinect and constant connection to internet will ensure our privacy? Despite the fact that those are only rumours, please take in consideration that every lie or assumption comes from at least a bit of truth.
