Not all Open Source projects are funded by venture capital! I work for a small company that has several Open Source projects out there, and has never had outside capital. We've had our bad times, but at the moment we are expanding slowly, and the future does not look too bad.
(And yes, we use Twiki internally, and I got the "relaunch" mail. Sounded like they wanted "strong branding" that was "not compatible with Debian". Pity, but if that is the way it goes, I will need to find another Wiki system for us, and probably convert all our data - won't let any single application dictate what distro I should use. )
