And... Apple will not be losing revenue in any changes they make. They'll simply make it up elsewhere with increased prices for products and services consumers purchase. And continue to set record-breaking revenue numbers every quarter.
Either way the consumer will pay.
To be fair... the biggest of the big developers (Netflix, Spotify, etc) have already removed subscriptions from the App Store.
So Apple hasn't been getting their money for years. Netflix stopped in 2018 and Spotify was before that, I believe.
It's unclear how "adding a link" will really affect Apple's income in any major way from now on.
Aren't most "reader apps" big media streaming services who can skirt the App Store and have users subscribe directly?
If this was about Candy Crush IAP... then yes... Apple would lose hundreds of millions of dollars every month if people could buy their gems or jewels or whatever from a website.
I guess I need to know what apps are considered "reader apps"
