Correct me if I'm wrong, but isn't the EU's stance 'all new devices from 2024 must have USB-C'? There is nothing to stop people using their lightning based iTosh long after that. Plus, it's not like all this stuff goes immediately into landfill; Apple gear has a relatively long life on the second-hand market so all the lightning cables out there will be used over time, companies just need to slow down production in tandem while USB-C production ramps up.
Apple are just clutching at straws because they can't arbitrarily lock people into their ecosystem and charge hefty licencing fees on third party manufacturers, although I absolutely can see them playing with USB-C's pinout so you need Apple certified cables to work correctly.
