If the courts haven't found in favor of companies using quotas as incentives, then you have no basis to claim that that quotas are legally acceptable as long as they're framed as incentives. This is directly relevant to your claims.
I find it noteworthy how often proponents of DEI talk in vague, euphemistic terms. You left me to guess what you mean by "certain groups of people". The group that I've witnessed benefit the most from DEI in tech companies is women - not Black people, or poor people. And the experimental evidence on the gender disparity in tech company recruiting does not back up the idea that women are disadvantaged when it comes to applying to tech companies: https://papers.ssrn.com/sol3/Delivery.cfm/SSRN_ID3946621_cod...

The courts don’t conflate these activities and as we’ve discussed, recruiting incentives related to broadening the applicant pool are perfectly legal and proper. This has nothing to do with hiring unqualified people based on identity as you imply. Hope this helps.
