There are several ways to build a business plan to make profit, and Google chose the one where they attract and retain an elite scientific and engineering staff in order to build awesome products, and so they respect the ideological lining of these staffs. Facebook insists more, in a more conventional way for sure, on marketing and business negotiations. Both approaches "increase revenue", of course, however not the same way, not with the same timeline (one of them is more long-term than the other), and, last but not least, not with the same heartburn when I read about it. PS: greater good is not opposed to profit. Your physician gets your money to care for your health. He chose this job rather than, say, the military.
