Is OSS on OSX just plain wrong?

All I wanted to do was check this list over at NewsForge on "Using open source software on Max OS X." What I found in the comments were some of the most vitriolic anti-Mac sentiments I've ever read. And I read that infamous Mac mini review a couple of times. The contention of several commenters is that Apple has 1) tried to make a profit, and 2) given nothing back to the OSS community.

I can't argue with number one there. Since we live in a capitalist country, it is fairly natural that a company founded by people who like to eat every day would attempt to create value and, gasp, profits for the company. Guilty as charged. I'm not sure why this is inherently evil, but then I never understood that whole Bolshevik thing either. I guess by this logic cars, gas, iPods, Cheetos, floor wax, and movies should be free as well. Good luck on that one gang.

As for number the second, I guess that's the topic for debate. How much has Apple given back? One person comes to their defense, citing Darwin, Konqueror KHTML, and OpenGL. I have to agree with OpenGL, because we really need that. Do we want another Microsoft monopoly (DirectX)? While there was a little controversy around Konqueror a while back, those issues seem to have settled down. Darwin though? Yeah, I guess that's an option. One of the best examples of Apple giving something has to be Rende...
uh, Bonjour. While it's still a pretty early stage for the protocol, I
feel it has tremendous possibility and has only just begun to be used.

As for the list at NewsForge, it is oddly placed. Apple has nothing to do with Linux. Most of the apps on the list we've mentioned here before: Adium, Growl, Seashore, Clam AV, Pixen, Vienna, Cyberduck, DTV, Smultron, VNC apps, and AppleJack. I can't seem to find Preferential Treatment though... I'm still not sure how OSS on the Mac is bad for OSS. How is it worse than OSS on Windows? And at the end of the day isn't anything not made by Microsoft a Good Thing(tm)?
