A vast number of web sites (probably the majority) do NOT use GA. None of mine, for example, and some of those sites are popular for their niches and get good SERPS even with panda (though I'm not betting that will continue!).
Quite apart from that, a lot of people (myself included) turn off GA in web browsers. I will not have anything google anywhere if I can avoid it.
And it's against their mandate?
