Your digital camera may embed metadata into photographs with the camera's serial number or your location. Your printer may be incorporating a secret code on every page it prints which could be used to identify the printer and potentially the person who used it. If Apple puts a particularly creepy patent it has recently applied for into use, you can look forward to a day when your iPhone may record your voice, take a picture of your location, record your heartbeat, and send that information back to the mothership.

This is traitorware: devices that act behind your back to betray your privacy.

It's a very disturbing trend. Companies will collect data about you and do god knows what with that data without your permission. It may be hidden inside giant privacy policies and user agreements, but is this behavior ethical or proper? Hell no. It's a giant game of privacy cat and mouse. Right now we have to fight for every bit of privacy because lawmakers don't legislate fast enough or even at all. Companies have thrown ethics out the door and will screw customers at every step to help their bottom line. What do we have left? Investigating, exposing, hacking/disabling, proxies/vpn, firewalls and refusing to buy software that violates our privacy.
