However, the contract is the only thing which allows Epic to publish in the store. So it is not enough for them to simply get terms they don't like to be declared illegal, they still would have to get the terms they like into the contract. If Apple changed their stance to "all services and digital goods associated with your app must included in the original purchase price", that might meet the court's requirements for legality but it would leave Epic without their current revenue stream.
