>I mean this seems very reasonable from Apple's perspective. They're trying to avoid their brand being tarnished by bad repair shops with questionable repair skills cutting corners with cheap and unsupported parts. Given how large the resale market is for Apple products I would even say that this is an extremely positive policy because as long as the machine boots you can be pretty darn sure your MacBook is just like you would get from an Apple store.

Apple's stance on "right to repair" is exactly about that. Introducing third parties into the ecosystem would drive down secondary market value for their products in a Gresham's law kind of way.
