Yes that is a very good point and I agree with Sgt_Kickaxe.
Though I am not sure how well they do it or how capable they are in reading the user intent i.e. commerce or information need in their users' minds.
And to play the devil's advocate here, how about they sending traffic to reviews and how to sites while showing relevant commercial ads alongside them? While it is true that every person intending to buy would like to be taken to a good review or how to site, the converse is not always true. There are still a lot of people who want to read the information on the web and buy in offline stores i.e. they don't have the commercial intent while surfing the web looking for products.
