There are job boards that SPECIFICALLY make it their business to target women and deliver female candidates looking for tech roles (in organizations that are in need of diversity hires): https://powertofly.com/ ...and companies pay a premium for those job advertising channels. Why is it a great business and an initiative to be applauded if it is about excluding men and a scandal if it is about excluding women?
The degree of “unfairness” is the same, but the goal isn’t “fairness” as such but rather equality. Whether we personally agree with forced equality or not is really beyond the point in a society that views inclusiveness as good and exclusion as bad.
