I have seen/heard of this in academia. The specific case I know about was a good chunk of a graduate math department. The attitude seemed to come from the top down mostly, but the graduate students seemed to repeat/reflect the attitude/culture.

Other conversations here give me the impression such ideas might be experiencing an uptick in expression, if not popularity in tech.
