All this 'right to privacy' and 'corporate spying' blather is just nonsense. It's a simple matter of control, that's it. People who increasingly feel that they lack any degree of control over their own lives, particularly in the workplace, due to IT departments reading every email, employers testing urine, etc., lash out at a visible, and, most important, solitary figure: some guy with a camera. They can't do anything about corporations reading their email and making them pee in a cup, but, dammit, this f*cker ain't takin' my picture!
And "corporate spying?" Please! There is no public space at the mall, or at WalMart. They own everything lock, stock and barrel. They tell you to put away your camera simply because they can.
