I think the article does raise some interesting points, particularly around the disconnect in non-technical people having absolutely no understanding of open source software and the lack of funding (including government tax incentives) to creating and maintaining open source software.

There are some projects that are doing well, completely unfunded by corporations, but they're definitely in the minority. And most of the successful ones have a freemium model or are related to piracy or ad blocking or some other philosophically- or economically-motivated project.
