Google is not an "advertising agency", that is a specific thing. What they are is a mainly ad supported medium which is what most internet services are, same as TV/Radio/Newspapers/Mags etc.

Airing out philosophical and theoretical disagreements with the ad model is merely a rationalization after the fact in this situation.

What are you trying to say? I should shut up, because nobody cares about my opinion or something else?
