I can’t find a list but it I think it’s safe to assume that some conservative media with advertising won’t advertise woke businesses eg the Matt Walsh Show (which you can fast forward to get to the adverts). Another would be any Elon Musk business.
However, for me DEI is just one factor pointing away from investment, on the grounds that it’s more likely to promote second rate people who will make damaging decisions, it wastes resources, and is a reputational disaster waiting to happen (the Bud mess has really stayed with me). I’m sure some woke companies are still great investments but imo it’s in spite of their wokeness not because and ultimately they’re playing with fire.
If MEI catches on I’ll post MEI business names here.
