Hah, so now setting up your own email server is Google bashing, running Linux is Microsoft bashing and drinking water is Coca-Cola bashing ...
In the end Google is the biggest advertising agency in the world. Advertising makes money by pushing people to make irrational choices - buy products and services that they don't need; buy from the vendor with bigger marketing budget, rather than superior engineering; overspend on stuff they need - e.g. cars, etc.
Airing out philosophical and theoretical disagreements with the ad model is merely a rationalization after the fact in this situation.
