“Want to buy and download a video? Fine. But Amazon’s Unbox program is going to run in the background on your computer and send information back to the company about your ‘operating system, software, amount of available disk space and Internet connectivity’ as well as what you’re doing with those videos, all in order to continue to ‘manage rights’ associated with them, says the agreement. … But if you somehow you violate their rules? Amazon has the right to reach into your hard drive from afar, delete all the videos you’ve paid for and not give you a refund.”
