The sentence immediately before the one you quoted is: "Remember how the open source software movement was supposed to be like Woodstock, with everybody sharing and everything free?"
I think the author wants to express that open source has changed a lot from the early days. As far as I remember it, open source originally was driven mainly by students, academics and hobbyists, and by service companies like Red Hat or maybe IBM. Nowadays, many of the larger, successful and enduring open source projects are mainly developed by professional developers working for companies that use the open source software for their commercial products or infrastructure.
