This approach finds its parallels in other collaborative spaces where meritocracy is valued; open source software development comes to mind. In that arena, this approach was widely deployed, but is at odds with the more recent trend of explicitly stating to promote inclusion and diversity.

Staunchly meritocratic online interaction and collaboration, from software development to messageboards, allows people to cultivate identities largely defined by their contributions, which is often distinct, or even at odds, from the identity they wish to demonstrate in their real life. In online spaces where individual contributors aren't restricted from speaking out against the leadership, this disconnect will manifest instead of being suppressed.

While I don't disagree with the author's recommendations and rationale, it's unfortunate that the OP's argument essentially reduces down to the fact that the less casual interaction between people, the more inclusivity will result. It's also re-framing the implied problem: the equality vs. equity debate. In the OP's view, the solution is to cultivate a minimalist, work-focused culture that solves the inclusivity question by avoiding it entirely. This is very much at odds with the approach that receives a lot more press these days, which seeks to prescriptively address inclusivity within its own problem-space.
