I don't really buy this. Have you seen Palantir's commitment to DEI?[0] How about Lockheed-Martin's commitment to the LGBT community?[1] On the flip side, I've heard plenty of people say Intel is a nightmare to work in, and they're (for the most part) fairly neutral in terms of "harmfulness." And hey, Blizzard-Activision just makes video games, certainly they have a positive and welcoming culture that cares about the wellbeing of their employees, right?
My point is, company culture is completely orthogonal to the industry a company serves. Pretending that big oil or tobacco employs exclusively people wearing 19th century robber baron outfits holding big sacks with dollar signs painted on them is naive. Everyone below the executive level is a person trying to feed their family before anything else.
