Well, It will definitely go through an appeals process, so it may be a year or more away. But I think it is a step in the right direction.
It was not a total win for Epic, the judge did not give them the right to create their own AppStore on an Apple device, but from the ruling that I read, it does give developers the right to advertise other ways to sign up. You have the right to tell users to sign up on your website, and install the app and just login. Also, I read that you are not limited to just IAP, so you can include links to pay by Stripe or PayPal or any service that you choose.
my apps are subscription based, so I will be able to let people pay with Stripe within the app in a web view is my current understanding.
And my hope is that in the face of competition, IAP percentages will drop to remain competitive and then I don’t have to worry about changing my code at all, which is the ideal situation, because IAP is convenient for users
