Apple used their own physical transceiver for the USB3/DP/TB port. They probably could have found an existing one that worked and supported Linux but it doesn't seem to be unreasonable to develop their own. To support the astounding bandwidth of USB3 and above these devices are a marvel of engineering. Every different cable needs the hardware to re-tune its timing and analog circuitry to match.

Sure, they can develop their own. But nothing is stopping them from also providing drivers/patches to the Linux kernel. Many companies that develop hardware do.

Apple is not charity. Why would they do that? It have to be economically justified.

They’d sell a lot more to Linux-only users… but that’s obviously not their goal, and Apple seems to be unusually good at being ruthless in their prioritisation.
