You are assuming things, my friend. I'm completely against drinking any kool-aid not only when it comes to Google, but anything. I base my opinion solely on facts & in this case I think I have access to more of them than you do.
Based on that I can tell you that the "Do no evil" slogan is not ridiculous at all & Google still bends over backwards to adhere to it. It's the most idealistic company I've ever been at by far. You can choose to not believe it & poopoo the idealistic principle it's build upon, but they take it extremely seriously.
I'll give you one example without disclosing anything I shouldn't. We have this product that competes with some other major websites & right now is nowhere near as used, right? So if we were as you think we could easily promote it by giving it preference over competing products. That's what any other company would most likely do. However, our search guardians won't let us do that. There's actually an excellent business reason for it. Google is the #1 search engine because of its credibility. Anything that would jeopardize it would jeopardize it as a company.
So any conspiracy theories about Google's bias when it comes to search results belongs in the trash bin & the people who believe it are the ones drinking the kool-aid. For example, some crazy conservatives who believe that Google's search results have a liberal bias despite the fact that it's very easy to see that that's a load of horseshit.
Your last complaint about online advertising is completely ludicrous. Online advertising is no different from any other. Yeah, we all hate it, but it's part of life in a capitalist economy. Blaming Google for it is like blaming TV/radio networks for running commercials. Same goes for any other media (magazines, newspapers, etc). Oh, and the last time I checked Microsoft's Bing was not ad free :)
