The judge ruled that it is ok for Apple to set and enforce their App Store guidelines. Remember that. Apple nuked Epic for running an unauthorized payment processing flow. And it was ok.

Apple is now forced to allow other payment processors into their ecosystem. But there is nothing in that ruling that says Apple can't make guidelines on payment processors and that Apple can't enforce them.

You had better believe that Apple is going to make a bunch of "consumer friendly" rules about transparency, data privacy, refunds, subscription cancellations, etc. And they are going to enforce them with no mercy, because the judge said that it is legal.

Also, don't be surprised if the "Free with in-app purchase" apps now have to pay Apple for bandwidth at whatever the prevailing AWS/Azure egress charges are. But that will be waived for using the Apple payment processor.
