In my experience, having worked at several large PSPs, it is Mastercard and Visa who are the morality police. Stripe are just enforcing the rules insisted on by them, and PayPal forgot about them 3 layoffs ago.
You said it was about morality, so it was not clear you knew it was actually about risk. Each payment company has to set their own policies because regulations tend to be (intentionally) vague and not all companies have the same risk tolerance. If the legal risks weren't there, Stripe would absolutely accept these categories. You should really complain about the dumb AML regulations instead.
