> Ads do get penalized for being a bad fit: they get a lower quality score and cost more.
My point is that as a user, ads, regardless of how "good" they are, are not what I am looking for when I click on a search result (I am talking about website ads and not ads on the results page itself) and thus a search engine that downranks pages with ads in favor of those without them would be beneficial for me.
It would be against Google's interest to implement that (as they'd also be fighting against their own ad network) but a different company not involved in the advertising business (and making high enough margins on other products) has a higher chance of delivering this successfully.
