The fact that major media publications carry stories on gender in tech but not in nursing, teaching, etc (or at least very infrequently) is a pretty good indication that the issue in tech gets more promotion. And this shouldn't surprise anyone; women's issues in general enjoy quite a lot more promotion than men's issues (e.g., "wage gap" vs workplace fatality gap, breast cancer vs prostate cancer, sexual assault vs literally every other kind of assault, etc).

This is me with my tinfoil hat on, but I think the real reason behind the push to get women into tech is to drive down wages by growing the labor pool. That's the real reason IMO that big companies and others are pushing so hard for women to code and to get into STEM. I don't think that these big companies really care about women or anything, but doubling the labor pool and thus driving down wages, now that's something I can really see big corps getting on board with.
