I also don't know if I would consider C/C++ or Python or the others success stories. They all have an ecosystem around them that allows for developers to be funded doing work on these projects, but only because of other products that are out there. Other products produce money, and are making enough to allow some companies and individuals to fund core technology improvements. That's different and a harder model to work with, because it requires massive scale to be effective.
