Evidence: Open source devs and Google and Microsoft have been trying to build MacBook Pro laptop performance for decades and failed. The entire performance advantage of Apple products is due to their tightly controlled integration of the hardware and software stack.

Apple consumers have come to expect this level of quality from Apple products. It is unreasonable for the EU to demand interoperability with other products when the very thing that makes Apple products work well depends on tight integrations that are not interoperable.

None of that has anything to do with secret/private API:s and corporate policies forbidding anyone else from using them.

In order to build a high performance product you have to control all of the API surfaces. Apple devices battery life would suffer if any shoddily written third party device could operate with crappy drivers for it.
