I don't think most people doubt the utility of Github, but this writing seems to be from a person living in a bubble.

Most people don't get the time and resources to work on open source. Some times, you can't even open source something, despite wanting to. For example, when I was in academia, I wanted to open source some worthwhile projects I had completed, but was never allowed to by superiors, because they considered them as competitive advantage IP.
