Claim number 9 might be right for the specific listed cases but it certainly isn't true for all domains. In the browser world, open source has clearly produced better results (chrome, firefox, webkit) than the closed source alternatives (IE before chromuim Edge). Also, this post is an insult to big projects such as Blender, which have been a terrain for innovation and experimentation for years. Blender is also is an example of long term effort and unified design. In the software library world, open source clearly wins in terms of market adoption and innovation. If the author has a car, it probably runs linux, sqlite, and many other open source components. In AI research, the common set of tools used by the community is open source (Tensorflow, Python, etc.) In conclusion, interesting perspective, but it does not match mine at all.
