I think you're simply completely missing the goals at play here. To your points about getting worse ads and creating an environment were worse ads are served ... that's the point. "Serving good ads" and "Having a reasonably accurate and reasonably complete profile of me" are different ways of saying the same thing in this context. The fact that you feel "I get good ads" is a good thing for users is the core disagreement you are looking for, this what you are missing. To the last point: Yes, those who benefit from the collection of their users personal data may be penalized by the system they benefit from when their users act against the interests of the ad networks. Again though, given the implied goals at play here, this likely isn't seen as a bad outcome but as incentive to stop funnelling your users information to a 3rd party for money. As an aside, your first point is wrong: You leak less personal information by this kind of fuzzing, they already have your browser fingerprint and so on, getting more copies of them isn't useful. Using an ad blocker is defensive, this is offensive. Which is better depends on your goals.
