Sadly it does nothing for gender equality at all.
The plenty of really competent women I know who have made it without the fanfare & chest beating, cringe at this kind of corporate nonsense.
Promote interest for both gender's in the industry at the grass roots level and let competence do the rest. If someone actively discriminates (I know of no-one who has/would), then that's a different scenario.
This silliness just invokes distrust and harms the very women they think they're supporting.
Remember, this as always, has absolutely nothing to do with notions of "the greater good". It's part of the narcissistic nature of a couple of individuals perpetually trying to raise their own "brand" profile....
