Re: it really isn't your hardware
I disagree.
There is a full OS running on a hidden chip inside the processor. I have no access to that OS.
There are plenty of secure or "not owned by me" processes, devices, etc running in my device.
Apple can decide to lock me out with an update because it does not detect the correct signature in the screen or the battery, etc.
Would you say your house is your house if you could not go to the basement or the attic? I wouldn't.
