That someone would think nerds are not competitive is, to me, the strangest thing about this article. Perhaps because I'm one, but whether it's Magic the gathering, Demoparties, rubics cube solving, chess, Counterstrike LANs, academia, or any of my tech jobs, every "nerdy" activity I've ever engaged with has always been overly competitive.
The fact that so many open source projects have had to adopt "code of conducts" is IMO a direct reflection of the fierce competition that has always been inherent to software development. Whether it's code quality, clever hacks, optimization... everything about what we do has a competitive element.
Come to think of it, I can't actually think of any nerdy activity that isn't, in practice, extremely competitive.
