Thanks for the summary!
By the way, would you happen to know if it possible to distribute the same app in the AppStore under the 15/26% commission and in alternative stores in the EU with the 10% commission?
Or maybe this somehow constitutes a danger Apple has to protect its users from, and can only be alleviated by me paying Apple the higher rate? The earlier terms certainly did their best to prevent anyone from opting into the alternative distribution terms.
As of 1 October 2026, you'll be able to distribute in the App Store and alternative markets at the same time. Apple charges a 5% commission on the latter, and the marketplace will charge whatever they like.
