Ok, fair. Then allow app developers to explain this in the app and provide a link to the external website and let the user decide what they prefer.
The issue is that you can't publish an app unless you hide this information from the user and as a consequence most users aren't even aware that alternatives exists.
Let the user freely decide and you can't charge how much you want for the convenience of your service, even more than 30%, nobody would care.
