Makes sense. If you're a junior player in the ad-serving space you can currently only observe the browsing habits of surfers accessing pages on which you have ads. Even on those pages, the trend is for the browser vendors to make this harder and harder.

People using VPNs are also probably the people using adblock and are harder to market to.
