"At least - thanks to the EU - soon they can all share the same USB-C charger."
The EU is basically the guy that at 5am declares that the sun must soon rise or else. By the time the EU decided on their USB-C dictum, Apple -- a co-inventor and standards participant of USB-C -- had switched their laptops fully to USB-C, their desktops to USB-C, and half their pad line to USB-C, with the rest coming not long after. Most people fully expected the 14 to be USB-C just because it was starting to be silly, and by the 15 it would be ridiculous if they still had lightning.
Apple was already switching. Which is exactly why the EU could go ahead and faced little resistance. The EU deserves zero credit.
And FWIW, the EU in 2010 dictated that all smartphones use micro-USB. Apple provided an adapter as they moved their entire line to lightning, thankfully, as micro-USB was a garbage connector in every way.
