The MEI grift is ~the same virtue signalling as DEI, with the sign flipped to try and appeal to culture warriors. Companies are highly incentivised to find talent and good companies are good at it, if they can find an angle to get people to apply to them rather than their competitors they will.
As an example: there’s a pretty straightforward financial incentive to make your tech company the place the cracked trans girls want to work/feel comfortable at - from a cynical perspective DEI needn’t have an altruistic component.
