Richard, please take a step back and consider the broader context of "don't be evil". In an earlier post you commented about Google indirectly profiting from this because they serve text ads alongside searches, but the vanishingly small percentage of queries that this represents is irrelevant next to the broader principles.

Google is a tech giant because they have done one thing better than anybody else: they connect information that is available on the internet to people who are looking for it. That is immensely powerful, and accordingly there are many ethical questions around who should be able to access what. Google has the potential to be the most terrifying censor in the world, and every government knows it. This creates a strong imperative: they default to open access, and resist attempts to restrict it. You are exactly saying that Google should impose their own ethical judgments on what appears in search results; please fully think through why this would be disastrous policy.
