This feels like it was written by a guy who wrote a popular OS and has had people kissing his ass for 15 years. Basically the coding version of a diva musician.
If you're going to ask me if I had worked on any OS kernels or distributed version control systems, the answer is no. But I would also never degrade people who might otherwise be willing to help contribute to my projects based on some idiotic notion of programming language superiority.
At this point I don't even expect anything better out of him because he did something great for the world. I expect better just because at this age he should be an adult.
