Again, there are plenty of instances where enough good comes from surveillance that it outweighs the intrinsic negative, but denying that it is, in of itself, intrinsically negative suggests that some creepy dude monitoring everyone's every move is just fine, as long as he's not doing anything else.

A more obvious parallel is violence. To trip over Godwin's law, shooting Hitler would have been a moral action, but not because "shooting people" is amoral. Shooting a random person is definitely immoral. We constantly do immoral things for the greater good, but it is a mistake to thusly assume those actions are amoral.
