I wouldn't have a problem with Google making money provided they operate the with their original intent (see video below for details). Indeed, ads are a good thing. My problem is the extent to which Google has become a monopoly (not good for consumers) and started skewing search results for either financial or political philosophical reasons.
Google is not neutral.
There are other options - Yippy, StartPage, Dogpile for example. They're all small potatoes compared to Google, but it doesn't mean they aren't useful, viable alternatives.
