I looked at the original search and while this text is there, and there's a colored highlight over the ads, I could imagine myself clicking the ad accidentally in a hurry, or someone less knowledgeable about the way Google runs Adwords to confuse the two.
I guess I don't really understand the problem here. If the ad is just as relevant (and if you're going to click it, thinking its part of the results, then I assume it is), what's the problem? If you don't like ads, use an ad blocker.
The title of a link isn't what makes it just as relevant -- if that was the case, what's all of Google's magic sauce for? Google does a pretty good job of ranking relevance, then sells the first spot to the highest bidder. It's a competely normal and ethical business model, but I can easily imagine people being ignorant of this.
