I have two devices that are just barely eligible for the latest iOS version but I don't want to update them. I have one iPad Air 3 running the current iOS and I don't like it. I also once got burned updating a barely eligible device and ended up having to buy a new one because the updated one was rendered non-functioning. My even older devices running on iOS 12 and not eligible for the latest iOS are still getting updates from Apple. But no updates from Apple for my two barely eligible devices so I'm assuming they are vulnerable since they haven't had any security updates in so long. Is this Apple's policy to withhold updates from users who choose to stay with their preferred version of iOS even though updates are available for that version? I do understand that at some point all versions are no longer supported but ios 12 is still supported and I would like to be able to have updates for my two devices.
