That’s a fair point. Apple has been known to do that in the past with FireWire.
But I guess on the issue of whether or not — at the time, two years before usb-c was readily available — apple should have used usb-c or lightning (the thing they helped make), you would assume they would go with lightning over waiting until an unknown amount of time for another plug to be available.
When I say they were stubborn to change from that, they were/are simply stubborn to change from that. I wish they would have pulled the bandaid off when they switched to usb-c on iPad.
Though, that said, barring speed/power, I do actually think the lightning connector is a superior design. It’s simpler, and there’s nothing to break inside the port on the phone/device. I wish usb-c was physically the same or similar.
