No, "fixing the pipeline" is also a red herring. The problem isn't "tech businesses should hire more women just for their gender" or "more women need to get CS degrees". The way you get to, say, all white men in your field is from attrition; i.e. all the women and minorities burning out and changing careers. That burnout comes from exploitative labor practices and workplace harassment, which are rampant in the tech industry - and especially in games development. If your business is able to properly enforce workplace rules against harassment, then you will have more women and minorities than other firms purely because they will remain at the company. No need for quotas, diversity hires, or affirmative action.
