I sort of agree and disagree. I will admit upfront I still cant articulate my thoughts very well on the subject matter.
I dont see why collecting 30% from Games is anything off limit. I consider Gaming as Non-Essential. If you dont like the Gaming Platform. Go Elsewhere. Literally every Gaming Platform collects 30% ( if not more ) on Games being sold. That is everything from early days of Nintendo, Sega, and now Playstation and Xbox. So in the case of EPIC, why are they happy with Sony and Microsoft charging them 30% on Playstation and Xbox? Whether they are losing money on the console sales is irrelevant in this context, that is their business model, and that is how the market works and accept. Nintendo is able to compete with a profits on both console and games.
However charging 30% on Apps, on productivity, business tools and when there are only One competing App Platform in the whole world ( of whole of US ) is where the question of Monopoly or Monopsony comes into play.
I dont think there is an easy answer. On one hand, changing 30% of subscription for Education and Fitness App is ridiculous. Apple being the sole buyer and pitching these client / business / partners against each other while benefiting from it is precisely the definition of Monopsony.
On the other hand, I would much rather paid this 30% extortion than having a platform where user can, no matter how difficult it may be, able to side load Apps. I dont want any of my family member doing it. If you really want the ability to side loads, Android it is.
I think Apple should just keep the 30% on Games. 15% of One Time Purchase Apps, 10% on Subscription and call it a day. I think that is a fair deal. Payment Processing, Fraud Protection, Refund and General Admin and Store Operation would have put it close to 5%. Business aren't losing much with the 10% Rent. With the lower commission Apple can better Enforce the Sign up rules. No more "Reader" App Guidelines. You are allowed to give better deals else where like on your Website. But as a consumer I am happy with the extra 10% for the safety of going through Apple.
And some additional info, it is estimated that 80% of App Store Revenue are from Gaming. So dropping the Apps and Subscription to 15% / 10% arrangement isn't going to make their services revenue collapse. Apple are also working hard on their AppleCare+ push, as you can now buy it within the first year of your purchase and Apple Store Genius has had their KPI percentage increased for AppleCare sold. ( Personally I think what is happening in Apple Retail is even worst than the App Store )
