I think that what underlies this fear of apocryphal “brogrammers” is the fear that, if everybody is left alone to do as they please without being brought to heel, every company will grow into a place where they, personally, don’t feel they fit in. It says a lot more about the authoritarian mindset of people who use the term brogrammer than it says about programmers and nerd culture.

Brogrammer is so amorphous it is basically a term for "I don't like them or their company so lets assign arbitrary sins to their strawmen as the other."

I have seen it used countless times as a term of economic envy in a "they shouldn't be allowed to do better than me" way.
