I think you're right; I can't seem to find anything that gives them special non-profit-seeking privilege. The only thing related is the "Don't be Evil" statement in their Owners Manual for Shareholders that states:

"Don't be evil. We believe strongly that in the long term, we will be better served-as shareholders and in all other ways-by a company that does good things for the world even if we forgo some short term gains. This is an important aspect of our culture and is broadly shared within the company."

I guess the exceptionally weak phrase "even if we forgo some short term gains" included in a non-legal document isn't really much protection.
