Nobody asks Apple to open source the drivers or firmware. I do not think that the "apple approved partners" have access to software that can at the same time diagnose a hardware issue and change the bandwidth or other parameters to illegal values. I remember one other issue , maybe it was fixed, but if you were a partner with Apple and someone had a broken product that needed a new part you had to first send the broken part to Apple and then they would send a replacement , so a customer would have to wait for days. It is a system that encourages the user not to repair and just give more money to Apple.
