I haven't used any iOS devices for a very long time. But do they still force you to use the default Apple apps? e.g. any web link automatically launches in Safari, if you want to use another browser you had to manually copy-paste the link into the other browser. Any maps link automatically launched in Apple maps, and any phone link automatically launched in their dialler. I don't remember any third party dialler apps for iOS but this was a long time ago. And of course, no option to change the launcher on iOS. If iOS still prevents you from changing default apps, I think that many would still think the Apple experience is limited.
