Under the App Store’s reader rule, Spotify can also include a link in their app to a webpage where users can create or manage an account.
Instead, Spotify wants to bend the rules in their favor by embedding subscription prices in their app without using the App Store’s In-App Purchase system.
I'm confused now. What is a "reader app"?
Spotify wants to make subscriptions an app functionality and Apple restricts that to it's own payment system - and the alternative they provide is external websites?
Why the heck is it called a "reader rule" and "reader app"?
