This doesn't particularly empower women at all; rather it sends very much the wrong message; "If you don't wait with having kids till later in life, then don't expect your career to take off with us." It may not be explicit, but it's certainly implied; all the denial in the world on the part of these companies won't change that. Plus, they couldn't possibly have picked a worse time to announce a policy like this. At a time when wealth inequality is at record highs, unemployment worldwide keeps rising, automation keeps making more and more jobs obsolete, they're essentially telling women that they should stop having babies so they can keep working nightmare hours for the big corporate overlords instead? It's like the executives behind this (and their supports) have lost all touch with reality.
Plus you know, it falls into a very conservative and traditional mindset of trying to control/manipulate women's bodies. You can pretend it's about giving them a choice, but when you elevate this to a policy instead of doing it in specific cases that are driven by the female employees themselves, you make it clear that it's not about choice at all.
