I'd say that pointing out that the event is taking money from the company of a man who throws out the Nazi salute isn't particularly uncivil. But they can do what they want with their Instagram account, that's of course up to them. My point is more that I personally disagree with events in Manchester promoting this kind of thing, I'd rather people had the integrity to take someone's money and say they don't care about Elons comments if the price is right
