Maybe other people's usage of the term is just different than yours without either being "correct". For at least half of America, "DEI" means "giving preferential treatment to some individuals based on their race, sexuality or gender". That might be a good thing (at a societal level it balances historical racism, or it counteracts unconscious bias or other contemporary inequalities) or that might be a bad thing (it's unfair to the individuals, it harms trust in the system and undermines meritocracy, visible attributes are a weak proxy to actual privilege) but that doesn't mean using the term the same way as hundreds of millions of other speakers is incorrect.
