I don't have a problem with the dominance of their search engine. I have problems with them using their search engine and other platforms to prompt you to use Chrome, or how they use their quasi-monopoly on Android app marketplaces to force manufacturers to preload just about every Google App in existance on Android phones. Then there's various Google services (some of them near monopolies) performing much worse on anything but Chrome.
If Google would be just search I wouldn't have anything against them, but they are notorious for using the market position of one of their products to push another.
