more specifically what DIE actually does is it sets race quotas. its literally affirmative action that was already tried and abolished brought back because larry fink has too much money and can basically decide single handedly who gets funding or not because of that.
its a subtle thing but it comes down to is the character black because it makes a good story, or the actor is damned good, vs what blizzard did where their internal documents show the overwatch cast was made because "we need Old Woman and Black Guy to satisfy the quota"
