Among the "historical principles of ownership" are those from the communist countries, where the individual humans had the legal right to own only things belonging to a very short list and nothing else.
However, USA has claimed during decades that such restrictions of the rights of ownership are an abomination.
Even if we would accept that this is just a modification of a contract between the "owner" of a device and Apple, if Apple would have acted in good faith, they should have offered that if you do not agree to let Apple run programs on your own device for their benefit, which was never mentioned when you "bought" the device, then Apple should fully refund everything that you paid for your device and other Apple services, so that you will be able to get an alternative device.
As it is now, you either accept that Apple changes their "contract" at any time as they like, or you incur a serious financial loss if you do not accept and you want an alternative.
This certainly isn't a "mutual, voluntary exchange".
