Could you make this quantitative? Say a "surveillance ad" costs X and a "basic ad" (no tracking, just common sense placement) costs Y. How much more is X worth to you than Y? There does not seem to be much data on this, but last I looked the value of surveillance ranged from worthless for all the effort (3Y at most) to utterly worthless (like 1.1Y).
