How many appeals ?
If Apple loses which on the reporting so far seems probable, expect them to appeal it all the way up through the legal system in the hope that Epic will run out of money before the appeal process concludes.
My own opinion is that the Apple store and the Google Play store should be limited to a commission of no more than 20% on the purchase of games and apps
and that developers should be free to use outside payment methods for in app purchases. I also think that it should be possible to load apps from outside the Apple store as can be done on Android.
