It's striking how much tech workers decry DEI on anonymous forums like Blind compared to the complete lack of dissent on workplace communications channels like Slack.
It's a prisoner's dilemma situation. Most people think it's BS, but the incentive to push back on it individually is almost nonexistent (because of the big downside) and so collectively we reach a shitty local minimum that could be overcome if everybody acted together.
At Dropbox in 2015 we had a diversity all hands in the fall or winter (November IIRC). Arden (head of HR at the time) flipped out when someone posted the question about more permissive hiring standards for women and URM. Then we conducted and anonymous survey asking people if our hiring process favored women and URM candidate and 83% said yes. Very awkward for leadership.
