I don't think the public good and making a profit are unable to coexist. Y Combinator has greatly aided startups, but has made a great deal of money in the process; Stripe and Amazon Web Services are very much the same. To be sure, there are some causes which can operate as charities; but if your goal is to simplify credit card processing for startups, can it be achieved in any manner other than in the form of a corporation? My own startup falls into the same category: I wanted the world to have a solid, secure, online backup service for geeks, and it turned out that a company was the only natural way for Tarsnap to exist. While I absolutely agree about the importance of open source software -- and that's how I've primarily given back to the community -- I don't think all the other ways people improve the world are in any way diminished by the fact that they make a profit in the process.
