HR run programs are costly and applied to either mandated trainings or things the org has issues with.

DEI isn't mandatory, so an org heavily invested in DEI training probably had serious issues in the first place (whether they end up on the other side at the end of the trainings being another question)

That's different from putting it as a core value though. Most companies have some kind of "make more money with less resources" stated value, and I don't think we see it as an issue ?
