This is the same Google that considers search engine optimization bad -- but doesn't hesitate to give preference to its own ads.
Google tries to paint a true picture of what's on the web, so it tries to deny people with optimization knowledge better ranking despite the site's actual popularity. Google never sold search rankings and all ads are prominently labelled as ads.
