Basically, hiring someone because they're from minority/vulnerable race/gender/etc.. to diversify instead of hiring the one that has the best skillset for the job

If we put the idea of Cobra effect aside, these companies are also trying to bargain because vulnerables and minorities would prefer to work for them than for other companies that don't express their preference of minorities, so eventually many of them will accept less pay to feel more welcomed, which is - in my opinion - pure emotional exploitation, they claim they have ethical reasons but actual many of them has only unethical reasons
