There is no doubt that the vast majority of open source software comes out of the software industry in SV. The arguing point I have is that it isn't out of an egalitarian view from the industry to provide for others and make the world better, generally speaking. Exceptions abound, sure. But the industry is busy making money, the fact that say Chromium and Webkit are open source is a very good example of how a company can use open source to leverage a competitive advantage.
My main gripe with the article is that it tried to conflate the technology movement and the software industry. Tied tightly together no doubt, but they are different. The very nature of the industry is to make money and that is totally fine, but let's not pretend the industry was some utopian ideal from the outset. As I said in my first comment, the industry specifically, grew out of the attempt to extract value from the technology. That's fine. It hasn't been twisted over time, it just is what it is.
I may have been flippant in my commentary.
