This kind of security should be tied to something like removable storage device where the users data is stored, not the main device itself. That way when the owner dies or loses acess then said owner only loses acess to the data and not the entire device.
IMHO this is Apple trying to force people to purchase new devices and prevent reuse. It doesn't matter what is intended on the surface, but what the actual outcome is. This causes more waste and it's not helpful to the environment. If you are serious about protecting user data tie it to hardware security that can be decoupled from the device itself.
I'm in the business of repairing computers.Apple is setting bad precedence on multiple fronts, More than any other company in existence.
