Comment business model (Score 2) 34
Not all of the code on GitHub is open source, but the majority is -- handy, when that means an account is free as in beer, too.
I'm not privy to any details of GitHub's finances or business model, but most likely it's a good thing that there are non-open-source projects using GitHub, because that's probably what's paying for the free open source use. I've recommended to several clients developing proprietary software the use of GitHub rather than running their own in-house repositories, because the interface is easier for them to use and they don't need as much in-house expertise to manage things. Because Git is distributed, they could of course do both, or easily transition away from GitHub later, and that's a selling point.
