Sure. All I'm saying, and I think what Semisol was saying, is that pure altruism isn't enough. Developers have to eat, too. In the case of Linux, after the first 5 years Linus' own work was supported by a job at Transmeta, then later indirectly by other companies via funding of the Linux Foundation. IIRC, there was also a gift of some Red Hat stock when they IPOed.
