that paper is very old. a lot of things have happened since then.
it's not about a search engine favouring advertisers anymore, it's about the search engine favouring the search engine's own products.
we expect that advertising funded search engines will be inherently biased towards the advertisers and away from the needs of the consumers.
in google's mind, putting youtube links and page links (for businesses) at the top of every serps is helping the consumer. they don't see themselves as an advertiser -- but in reality they are. they are advertising their own products
