I dissagree. Altruism itself is by definition not a profit motive, but only a very simple robot or a computer could possibly be driven by a single pure motivation (seek light, or some such.). I am always motivated by multiple things. Greed, desire to do good, desire to be seen doing good, laziness, boredom, desire to learn something new, fun seeking, thrill seeking, etc. all play a part in what I choose to do at any one moment. Even if it's 90% profit motive and 10% charitable motive, perhaps the project would have been ignored without that other 10%. And even that is too simplistic. If they are even remotely human I would guess you could easily add in, desire to be admired, desire to solve a difficult problem, ego, adventure, and a long list of other motivations for this single project alone.
