> And, I don't think you can say "nobody is successfully using ads to determine ad clickers general location with a X mile radius".

Of course. And I'm sure that you can find some people who would get riled up that they incremented a counter in a location-oriented semi-anonymous bucket of clicks. But I think most people are substantially less riled up about that than they would be if Google were actually disclosing their individual locations directly to buyers. It seems like a lot of the anti-Google folks on here equivocate between these two, and I speculate it's because consciously or subconsciously they realize the latter narrative is much more emotionally compelling to a much broader segment of the population. To me, that's deceptive rhetoric.
