I think I agree with your sentiment, but should the GP be worse off for being honest/pessimistic/seeing things clearly? I'm sure there are lots of people doing what the GP describes that don't feel they are doing anything immoral. Are they in the clear? If you're actually participating in fraud it's one thing, but doing something legal but morally dubious like working around browser privacy comes down much more to individual perspective.

This potentially is another argument for laws / regulation.
