Yes, it is. The problem comes in when a company which controls a significant percentage of one platform (search, in this case), uses that advantage to muscle in to other areas. This is seen as a bad thing, because beyond the consumers are left with an unbeatable giant. Unlike normal market leaders, however, this giant doesn't need a superior product, but only apply leverage (given by their other positions). This is the very essence of anti-trust / monopoly laws. Competition is a good thing.
