I can't speak for anyone else, but I find that a little evil.
Plus these look more like customized brand pages for companies that people are "specifically looking for", I would rather have detailed information about a company right front and center when I'm looking for it. The fact that anyone makes money because of this fact is ancillary.
I'm having a hard time not reading this as effectively saying that it's evil to compensated for providing a service.
Yeah, it's probably the most relevant result, but it's giving the user (especially if that user is, you know, non-technical) little choice but to click on the thing that puts money in GOOG's pocket.
But the user made the choice to use Google in the first place. If people don't want Google getting money for clicks in their search results, then they should use a competing search engine.
Southwest probably knew this when they negotiated with Google for the giant front-page ad.
