I specifically said the physical design of Lightning is superior
In your first post you said that. What you asked was “what is the advantage of using USB-C?”.
If you’re going to be so blatant as to ignore the advantages of the USB-C standard purely to focus on its one disadvantage over lightning, being durability (due to the exterior facing pins) then I might as well not even be talking here.
The iPhone and all of Apple’s accessories (such as AirPods) used Lightning up until a couple of months ago. The keyboards and mice still use Lightning. A connector used on well over a billion devices has all of the practical advantages for consumers of being a standard even if it’s nominally proprietary.
I’ll concede part of my point as it was not all of their products that made the switch, but some of their products made the switch as far back as 2018, like the IPad, so far more than just a couple of months ago.
USB-C is also a standard used on well over a billion devices - should Apple get special treatment when it comes to having to play nicely with everybody else?
Yes, which is why companies should always be reluctant to change unless the new option is significantly better. Lightning was way better than anything else available and was worth the inconvenience of the change. The benefits were real and obvious to all users. The transition to USB-C is … less compelling for users.
It is significantly better in almost every way, but you won’t acknowledge that because you want to focus on the one disadvantage of the USB-C standard.
If Apple takes advantage of the higher technical capabilities of USB-C, then the benefits will be obvious to users as well.
I mean if Samsung can use USB-C to allow their phones to become mini-PCs, then Apple can surely figure out a good use for the extra horsepower of USB-C
