I don't claim that advertising is the only vector of influence, and I realize it is possibly the least worst version (because of labeling), but that hardly seems like a reason to consider it a Good Thing. Your argument seems to be that if we get rid of sponsored search results, this will push advertisers to invest more heavily in less visible forms of opinion manipulation. This is actually a very interesting viewpoint and possibly a valid argument, but it also feels like coercion in some way ("give us ad space or we'll reach you via less ethical methods").
