I don't want to get into this on this discussion because...well. video games. But consider the following: The organization and customers benefits from meritocratic hiring of the best candidates. But individual hiring managers have biases either for specific people (nepotism) or against groups of people (bigotry). Those individuals would be acting against the best interests of the company and customers whether they act consciously or not. A responsible company would adapt hiring processes to remove that kind of bias otherwise everyone suffers. The company suffers due to lower efficiency and blind spots in their points of view. Customers suffer due to worse output by the company. Some individual candidates suffer by being denied opportunities based on attributes they have no control over (gender, race, physical appearance) instead of the merits of their education, experience, and talents.
There's no single way to do this but people have lumped them all together and called them "quotas" (they're not, at least not in responsible processes). It really does a disservice to the fact that it's encouraging meritocratic hiring. Because for most of the 20th century (and even still today) employment was and is stratified by race and gender, not ability.
