I think that people confuse the tech-bro subculture with the wider developer subculture. My experience has been that the developer subculture is often more progressive than libertarian.
Where could we find a definition to check that we were referring to the same thing?
Modern progressive anti-meritocracy people might be loud, but they are a small minority, even at Google at the height of progressivism there you would see pro-meritocracy views winning out strongly among developers. You also see it here, I feel most here on HN are pro meritocracy. There are some progressives around who go into every thread about the topic and post a lot, but meritocracy views and topics tend to get upvoted.
