The original post in this thread was:
> This is because Carmack doesn't really do OSS, he just does code dumps and tacks on a license ("a gift"). That's of course great and awesome and super nice, but he's not been painstakingly and thanklessly maintaining some key linux component for the last 20 years or something like that. It's an entirely different thing; he made a thing, sold it, and then when he couldn't sell more of it, gave it away. That's nice! But it's not what most people who are deep into open source mean by the term.
Skrebbel probably shouldn't have said that Carmack "doesn't really do OSS", but what they clearly meant was, Carmack doesn't participate in the sort of community development as the Linux kernel or Apache or whatever.
