I don't believe any specific action needs to be taken to promote diversity. As far as I can tell, people can work wherever they will, as long as they can pass the interview.

Please name these.
Do you think discrimination just ended immediately after the civil rights act[1]? Personally I don't think peoples mentality changed at all just because certain practices became illegal, it just got less overt. Saying "women aren't cut out for our line of work" became "not a culture fit" or something else.
Its not my goal to try to prove discrimination exists and existed, I could search and try to put together a comprehensive list of first-hand stories about discrimination in tech but my guess is that would not be an effective use of my time and that isn't the goal of my post anyways.
