All abstractions are simplified. That's what makes them both abstractions and useful.
For example Google Search might be considered a marketplace, but such an abstraction might lead a person to lump buyers and sellers into amorphous blobs and ignore the heterogeneity within each group. Ford and overstock.com are different sorts of advertisers and thus Google's business comes down to segmenting end users.
Plain and simple the most valuable end user segments are people who not just tolerate tracking and targeted advertising but who actually derive value from it. They are valuable not only because they click through and buy stuff but because they validate Google's claims that its business of tracking users and pushing ads and tailoring search results toward commercial interests and away from the long tail is objective.
Long tail results are not revenue generating and Google has simply removed bit by bit the end user's ability to specify them. Sure spelling correction is useful, until Google search refuses to respect quotation marks and simply renders some terms unreachable. Local search is useful, until a person wants to search across borders or outside their local language.
