I mean this really just boils down to whether or not you care. Personally, I don't because I don't do anything illegal. If they want to watch me scratch my nuts in front of my tv while I play Destiny, they can go for it.

NSA wise? I don't care. I've got nothing to hide. XB1 wise? I plan on covering the kinect lens. I will never use it for anything, and don't want anyone looking at me.
