Not arbitrary, but morality plays a role because the industry is afraid of public pressure and potential legislation. There's been significant lobbying from elected law enforcement and religious groups. For example: * https://www.eff.org/ja/deeplinks/2015/12/sheriffs-threats-against-credit-card-companies-violate-first-amendment https://www.eff.org/ja/deeplinks/2015/12/sheriffs-threats-ag... * https://www.bbc.com/news/world-52543508 https://www.bbc.com/news/world-52543508 Take the second campaign linked. It went beyond advocating for the current law to be enforced and also advocated for cutting off morally reprehensible content (such as content that fetishizes racial slurs) from the global financial system. I'm not saying that's wrong, I'm saying that it's a moral judgement.
