Functionally, isn't that much the same as disabling an Android system app? I wonder if these articles would cease if Android simply changed the label "disable" to "delete" and removed the ability to view and re-enable disabled apps.
Android system apps can be reenabled without redownloading them, IIRC. On iOS you must download the app again to use it.
There are some built-in iOS apps that can't be deleted at all, such as Photos. For those that can be "deleted" Apple says users can restore them by downloading the app from the App Store.
But if a user deletes all the built-in apps that can be deleted, are they restored if the iOS device is reset? I would assume so, since wiping a phone is recommended before reselling it and a new user may be confused if default apps are missing, though I don't want to wipe my device just to confirm.
