What they are actually saying to you is that they can't verify that you are an authorized reseller of anything with the Apple brand and they are not willing to take the risk. They really should have just said this to you but this is what they mean. If you are not an authorized reseller, it is possible for Apple to sue them for processing transactions for products sold with the Apple brand without legal authorization from Apple. If you can prove you are an authorized reseller, they may allow you to continue to use the Stripe service. I hope something can be worked out. Third Party payment processors come with their own set of weirdness.
