Payment processors generally don't refund fees on payments when the payments are refunded, this isn't new. It's remarkable mainly because (a) it's 30%, not 3% and (b) the App store doesn't position itself as a payments processor the way Stripe does, so it sounds really weird that they would act like one.
If the app store took a 3% chunk and never refunded it regardless of the ongoing status of the transaction, that would put them right in line with other payment processors. It would also still net them billions of dollars, I think!
