It's not limited to HN. Even in a local dev Slack community, I often see people expecting companies to flagellate themselves just for a chance to hire the unique, special talent that they believe and need constant reassurance that they are. As far as I can tell, it's unique to tech because that kind of talent is in demand, but the toxic behavior it brings out in some people is really something to behold.

I prefer to know my value and vote with my feet. No pontificating required.
