Expiration after installation makes sense from the perspective of planned obsolescence, and in anticipation of long-term-support sunsets.

It makes absolutely no sense to the end user, acting as possessor or potentially a reseller of an object, since the very premise implies that an owner should not be provided total control over their device, that it's never really "theirs", and that a vendor should retain the capacity to take a "sold good" away from the owner, under the guise of expected behavior, built as designed, effectively converting a sale into a rental, in time, perhaps after statutes expire.

It's effectively a back door for manufacturers, so that they can count on well-made products not lasting forever, not in museums, not for resale, not for nostalgia.
