in related news....my point was not that they are ads but that ads are probably 90% of the page. To the unsuspecting user, those seem like unbiased results (not as ads) and to everyone they start the "Google tax" price increase for everyone.

Try "geomorphology" or "big o notation" Go and buy those keywords and see what happens. Google posts ad for bought keywords and that usually includes every commercial word. If the defense is that not sure if you're helping them.
