I personally reckon that making Google Search a significantly worse product is part of the reason why this happened. One of the companies pushing for this is Ciao, a comparison shopping service owned by Microsoft and used to provide the equivalent feature for Bing search results. Microsoft clearly know how useful these kinds of contextual results are, because before Google had them they were promoting them as Bing's big advantage over Google. Now they've managed to get the EU to restrict Google's ability to compete by offering them.
