Their search homepage was supposed to be minimal. I was at a tech talk given by Google sometime around 2012 and they said that their ad service is not under any circumstances allowed to slow down the page load - if the ads don't return before the page is ready the pager is rendered without ads.

Chrome had so many great ux choices originally, such as tabs all staying the same size when you were closing them so that you could close multiple easily and only resizing after a second or two (that stopped working around a year ago). Hell there are even rumours that Chrome is called Chrome because it was a polished UX.

Their original products were so smooth compared to what was there before. Search compared to altavista, mail compared to Hotmail, both compared to Yahoo!. I really don't know where your perspective comes from. GCP?
