Google has a dual-class stock structure which gives class B holders (Schmidt, Page, Brin) 10 votes per share v.s. 1 vote per share for the rest.

This is relevant to your statement, because while it's pretty much a requirement for a publicly held company to pursue profit at any cost, it's not necessarily the case for a company run by the people that have a disproportionately large number of votes on major issues.

I'm pretty sure they still have over 50% of the votes, so together they can decide how Google will handle tough moral issues without any support from other shareholders.

I would argue that it's entirely plausible that a couple altruistic billionaires will sacrifice a few dollars in pursuit of non-evil (their opinion of non-evil mind you).
