I want to be FEARED!
The reality of it all is that privacy is an illusion these days.
From our computers, to our phones, to our cars, as nothing else is really private.
If someone wanted to, they could easily find a way to watch you (even find out exactly where you live), and the only thing with Kinect 2, is that it is obvious about it (on the listening/watching).
If you are still worried about Kinect "listening" then, I would say to get this, as you could make sure the Kinect isn't drawing any power, more than just from a setting on the console.
Then again, I think you should be more worried over some other things listening to you.
Or don't buy the POS.
