It's pretty simple. Developing and sharing open source work is paid hobby at best. There is almost no other rewards, even to try improving one's employability is hazardous at best. Always have, always is. This a cause a lot of frustration to people that expected anything else, but it's true to most non-economically motivated work. It's done, or should be done, by people that want to build things they like and share it. Any other use is just some kind of hidden or not so welcome motive, and seen for what it is. Billion dollars companies or not.
