Identical components from two identical devices ought to be interchangeable without manufacturer intervention

I'm mixed on this. On one hand, I hoarded laptop parts to repair mine when Apple purged Amazon's site of 3rd party sales. (That should not have been allowed, but another topic for another day) But on the other hand, I've had a device stolen and harvested for parts and these annoying locks probably disrupt that market.

I would suggest, if a repair involves a manufacturer intervention, that it be readily available and free for verified owners.
