Not trying to defend Apple here, but we should keep in mind that the goal for Apple is to prevent such photos from being uploaded to iCloud and detecting those that do. If someone turns off iCloud sync, then Apple would argue that it's not their concern to scan photos saved on devices (and thank god it doesn't otherwise the repercussions would have been much more significant).
