This is great! The push by large companies to replace personal asset ownership with perpetual rent is worth fighting against.
Suppose some hardware is sold to you, in the ancient ownership sense[1]. Then some time later, the maker decides that you must use only authorized parts, or they will not continue to provide a cloud service for it, or that it's just plain EOL. Then, you never really owned it - you were renting it. So was that original purchase actually a lease, but misrepresented?
Part of the solution may be legal, but I also think that the architecture of the device will need to change, e.g. to remove the technical ability of the manufacturer to remotely brick it.
