If you're saying "group X is inferior and and I can prove it mathematically", that's still wrong because those people don't have a choice about being a member of that group and still exist in society. Discriminating against them drags society down. It's a prisoners dilemma. If everybody hires fairly then the relative drag is spread across the entire economy and everyone comes out better in the end. If they try to cheat then they'll have a local advantage but in the end it only encourages everyone else to cheat and you end up in the worst case scenario with the massive drag on society as a whole.
So the only rational solution for these corporations is to pretend to be as inclusive as possible while secretly trying to cheat as much as possible, which is exactly what we see. When some dumbass publishes a paper to the entire world saying "Hey, we should openly cheat.", of course he's going to get fired.
