The more interesting issue to me is the accusation that Google violates antitrust law by boosting its comparison shopping search results in its search results, unfairly disadvantaging competing shopping services and not delivering best results to users. What's interesting to me is that the Commission is attempting to portray general search as a separate market from comparison shopping search, accusing Google of attempting to leverage its general search monopoly into the separate comoparison shopping search market. At first blush, Iim not convinced that these are or should be regarded as separable markets. But the ramifications are enormous. If that is a separate market, then arguably so is Google's book search, its Google Scholar search, its definition search, its site search, etc. It isn't clear to me how one might draw a defensible line taht does not also sweep in every new search feature  as a separate market.
