They have had stuff like this for years, and it's one reason I don't have a web cam on my monitor, or with the computer. It's digital, it CAN be hacked.
Google, even they got in a pickle a while back where apparently it could use a "hack" to turn on microphones unbeknownst to the user, and it would listen for key words, all of which to base user based advertising. SO say you are talking about the latest new set of pans, you log on, go online, and get ads for what you were talking about.
Granted, that is far more benign than THIS, that sh*t is just nuts, scary, and makes me realize just how everything with an eye(digital or not) can track ya. Nuts.
