Collective madness is largely reached at this point: the writer is complaining about a totally self-made issue. If I was trying to recruit men for nurse jobs, or people of color in Korea I would ran in a similar pipeline problem. The real issue is that "diversity" had became a metrics to reach for its own sake by companies instead of simply recruiting people that fit the job. Moreover, you can’t complain about so-called systemic sexism or racism when your policy is to not recruit white, asian or men that could fulfill the job precisely because of their race/sex.
