I would say open source creates new opportunities for developers. Instead of paying a developer to implement their own JS view library and then use it to solve a problem, you hire the developer to use React to solve 2 problems. That said there is an aspect of AWS (etc.) making money off the back off the efforts of certain open source projects. Stock illustrations on the other hand are a direct replacement for artist's work. If I find a logo online, I don't need to pay someone to design a logo.
