>Apple may not design for repairability, but what you are saying is not true. I have personally purchased and installed genuine replacement displays on MacBooks with no involvement from Apple.

Which year?? It used to be like that, no anymore.

It is public knowledge that Apple has locked its hardware via firmware. It must be performed by authorised only. You can check YT, that guy in the USA that defends the "right to repair" movement, etc.
