> why not fix the way the mentioned biases
What if the biases are deep-rooted and subtle and difficult to address without destroying productivity with endless ceremony? What if the biases exist beyond that single organization's control, but still affect them? If the waves are pushing you in one direction, pointing your bow slightly in the opposite direction might really be the right thing to do.
> The idea that the best way...
Few think it's the best way. The problem is, eliminating systemic bias will take a long time. During that time, new victims of that bias will continue to be created. If the introduction of a contrary bias helps more people than it harms, is that really so crazy?
