They always address the two main questions/premisses "more women needed in tech" & "why are fewer women in tech" flippantly with weak, unthoughtful arguments & cliche explanations. Both are genuine questions that need to be addressed. Even if you are willing to accept that women need to be equally represented in tech as self evident or fundamental, you should still find out the real reasons why things are this way if you want to fix it.
Any answers that you come up with to the "why" question need to answers it in a way that doesn't equally apply to law, medicine, academics & government. Professions that women entered a generation ago.
In any case, I'm only half convinced about the economic rationale given by this article: We need women to design stuff for women. It is a definitely a real problem people designing tech products are disconnected from many of the people using tech products. But women are the one "group" that technology designing men do interact with. I think if you want to add useful perspectives something to encourage might be technology as a second career. People who spent 10 years as farmers, nurses, builders or rodeo clowns.
