Apple has done exactly this before, with the "repair" for the 2011 MacBook Pro's that had "RadeonGate". Yes, they exchanged the non-working motherboard for a working one. But it was THE SAME motherboard, and could fail again. And often did.
I sense this is what they're doing with the MacBook Pro "topcases", too. Just "swapping them out".
I wonder what happens to "the bad ones"?
Do they get broken down, with parts getting re-used?
Or just "into the landfill"?
If that latter is what's happening, seems like the 2016-17 MacBook Pro's could become one of the most "environmentally-UNfriendly" computers ever...
