One could argue that the spirit of the law is an aim to reduce e-waste, and changing iPhones to USB-C will render literally billions of Lightning to USB-A/C cables useless within a few years. But there's obviously the argument that the existence of a need for those cables is in itself a source of e-waste production... I swing both ways honestly, I love many engineering aspects of the Lightning port, and at the same time I recognise that having only USB-C to care about would obviously simplify my life a bit, even if I think for the purpose of a mobile phone it is an inferior port.
