That was the obvious rebuttable, and to be honest I have a hard time countering that however the obvious statement is search really a market since it is a "free" product. One has to ask what is the actual market, is it the search engine or the advertising that pays for the search? Google while dominate is not a monopoly for Online Ads, so while they command a 90-95% market share in "online searches" that is not the product they sell so traditional market dynamics are not at play so I am hard pressed to call online search a "free market" given nothing it being sold, what is being sold is the ad space on google search.
