What would IBM lose if they supported a holocaust again? Well - presuming we defeated those bastards again, they’d lose everything.
Why do you think this? I'm actually curious. Volkswagen, for example, was literally a company that exclusively worked with the Nazis. After the war they were expanded to be even bigger. How many companies were actually harmed by working with the Nazis? How many have been harmed recently by working with fascists/extreme right wing groups?
Edit: I thought I should add this here: https://en.wikipedia.org/wiki/Just-world_fallacy
