Apple itself for some time had only one charging method, 1st MS (well, others before, but we don't need to go there), then USB-C and then decided they liked both.
So, no, the EU had nothing to do with it.
Sounds like an agree to disagree.
IMHO Apple saw the writing on the wall with the EU mandate on charging ports and implemented both. I don't see how it could be argued that USBC is a superior charging platform for laptops over MagSafe, I hope Apple keeps it while being forced to support a separate and inferior technology.
