“[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.

iOS 17 to Support App Sideloading to Comply With European Regulations

Apple in iOS 17 will for the first time allow iPhone users to download apps hosted outside of its official App Store, according to Bloomberg's...

@marcoarment I agree with you on the way Tim Cook sees this, but I also think once sideloading is possible, Apple will start to lose control. And that's how it should be. Are they going to sue small developers to access our bank accounts? Ridiculous.

@manton "Ridiculous"? Why?

You think a little uproar from some developers would dissuade them? I think not.

Non-developers will think that that is fine.

@clonezone It's just wrong for Apple to claim a portion of my revenue that they had no hand in. I agree non-developers will not be very concerned about this.
@manton What you consider to be wrong and what Apple considers to be wrong are two different things. Apple feels justified and all the stuff that has happened so far in Asia and Europe shows that they will get away with requiring reporting of all outside-of-store revenue and paying ~27% of gross.
@clonezone I don’t think they are going to get away with it long-term. Might take years to sort out, though. And yes, me and Apple disagree. 🙂
@manton Unfortunately, I do not share your optimism. Yes, they're going to be forced to allow out-of-store sales. I don't see anything forcing them to reduce their share of revenue.
