I was thinking about this today - they should drop the commission to 10% across the board and change the policy on IAP. For in app media subscriptions, 0%, but stick with Apple Pay only for IAP. For app/game features exluding streaming media, 10%. IAP for game 'content' such a lucky dip boxes (the crap that Epic wants to sell) 100%, because selling this shit should be totally outlawed.

Edit: Allow a mechanism for chargeable updates.
