> That's on app developers (I suspect mobile game developers are not the most competent of the bunch). My entire iPhone's backup is 4.6 GB, and my YouTube downloaded videos alone are way more than that.

While it's the app developers that need to make the change, it should be enforced by Apple. After all, that's why there is a walled garden, and that is the premium we pay for when using Apple.

But for Apple to enforce this means less popups on screens telling people that storage is full, which means less sales.

And again, we get to Goodhart's law.
