Think of it this way. Ever see the movie where they put the neck shackles on people that blow up if they do something wrong? Running Man is an example. With local device scanning, I feel apple is putting a neck bomb on me, but promising they won't blow it up unless I do so and so. I can't take the neck bomb off and never should have let them put it on in the first place. My head is now at the mercy of Apple now and forever because it's locked on. Now Apple can change the terms of service, boom. Apple has a bug, boom. Why in the hell would I want this neck bomb on me?!
