For the most part, people aren't trying to discriminate, nor to offer opportunities to some groups but not others (there are exceptions, but they're relatively few and more powerful for signalling than for direct impact). What they're trying to do is remove currently existing impediments to women entering tech. Improving CS101 classes is a great example. There are many forms a CS101 class could take. But they're generally taught by men, and they've generally been taught to young men. It's not implausible that they might be unnecessarily hostile to women (or to take another angle, biased towards backgrounds that women are underrepresented in, like "people who consider themselves gamers"); not through malice, but just through habit and happenstance. It seems very plausible to me that these classes could be more inviting and inclusive without compromising academic integrity. That's a win for everyone. It doesn't engage in discrimination: it just aims to remove an existing (albeit unintentional) impediment.
