According to the OP, since Google makes most of its money from ads, they somehow only want to strategically pursue ad-based revenue. This is beyond stupid analysis. Literally every business on Earth would like to diversify their revenue stream if it were possible to do so.
Besides there are plenty of examples where Google earns revenue that isn't from ads. See: Google Apps, GAE, GCE, etc. etc. If "We Are An Advertising Company, You Are The Product (TM)" was Google's ethos and defined all the work that they do they would not have built those products.
