Because raising money is their main goal -- diversity and inclusion are not part of it at all (when they don't actively hurt, e.g. if most good programmers are white+male in your area (which statistically is all too probable, if not for anything else, because those are that had the money and where encouraged more to be programmers in the 90s and 00s when they were growing up), and you need to get an equal number of token women+minority programmers just for diversity's sake).
