Pissing off advertisers is not a great business strategy. It’s not that their feelings are hurt, it’s that ads for Pepsi and Apple were showing up next to neo-Nazi posts, giving users the impression that the advertisers actively endorse the posts. People generally don’t like being associated with Nazis. Maybe you’re comfortable with that association (if so, seek help), but most of us aren’t down with genocidal maniacs who want to purge the world of non-white citizens and rule with an iron fist. I know, we’re funny that way, not wanting to endorse and spread the sentiments of mass murderers.
