>is really people pushing back against the notion that weird or bad behavior is a signal of greatness, or that productivity means you can treat people like shit.

Exactly. No one sensible disputes that, given the right circumstances, some engineers (or business leaders, etc.) can bring more value to an organization or culture broadly than ten or more people who are just OK.

But pretty much everyone I know who I consider exceptionally valuable is also good at working with others and enabling teams to be successful.
