People getting paid to do things do worse than otherwise[1]. They do better when not paid. The quality of work often gets worse when they get more. It's well established. As counterintuitive as sometimes it seem to be.
What I'm essentially saying is, if you think people are right now getting paid to do something bad to the society(e.g. ads), you might want to keep them hooked and tied to the money and not to something else, like advertising for its own sake.
