So your retort to "Apple doesn't believe that you should own your computer" is essentially "if you just don't connect it to the Internet, they can't control you"?
It's not a bizarre position to take when someone wants something to come live in your digital home.
I'm not saying "Tim Cook has something to hide because he won't show us his private life". I'm saying "Apple wants to send a machine to come live in other people's homes; if they won't show the machine's insides, I wouldn't trust that they've got nothing to hide".
