“[sideloading] would allow customers to download apps without needing to use the App Store, which would mean developers wouldn't need to pay Apple's 15 to 30 percent fees.” https://www.macrumors.com/2023/04/17/app-sideloading-support-coming-ios-17/

Not a chance. Apple will just use another method to collect their "commission”: https://developer.apple.com/support/storekit-external-entitlement/

Remember: Tim Cook views our customers as THEIR customers, our sales as THEIR sales, and the 30% as what they rightfully deserve for gracing us with a platform that we provide no other value to.

Soon, at WWDC, lots of great people in developer relations and engineering will tell us how important developers are to Apple. And I believe them! They've shown in many ways over the years that they truly appreciate us and the value we bring to the platforms.

But they're not the ones making IAP policy.

Tim Cook shows us, over and over again, exactly what he thinks of us, and exactly how he thinks the value flows between Apple and developers.

When someone shows you who they are, believe them.

@marcoarment I can’t help but feel if Apple had lowered their cut to 10% or something similar early on and said “this is for you, because we appreciate you”, so much hassle for them could have been removed. Greed is what it is though.
@cabinet20 @marcoarment Could it though? I mean it’s essentially 15% now, and even at 10% would there really be no more complaints? I doubt Epic would have accepted that.
@tuckerjj @marcoarment People would definitely still complain but dropping their cut by 67% may have stopped the governments getting involved. Honestly, it might not though. Certainly it would have limited their bad press from developers though.
