I’ll give them some fairness. When lightning originally launched, it was a great interface for lightweight power delivery and was more sturdy than the deplorable micro USB. I can’t explain just how bad microUSB is. So it made sense. I think USB-C just put in the legwork to be a much better adapter.
Also the giant plot hole missing here is that Apple sits on the USB forum I believe and so has some say in what the billions of devices they produce use to charge. They just can’t make money off of a standard now.
