There wasn't a law mandating the use of the old micro-B port. The EU issued a memorandum asking companies nicely to use micro-B, but obviously it wasn't enforced (Apple never complied).
This situation is different. Apple and others are completely unable to upgrade to USB-D when it comes around.
No, they are not. They will be able to use USB-D in parallel with USB-C until USB-D becomes industry standard, at which point it will be adopted by the EU as the new mandatory standard port.
And during that transition, exactly like now with the Lightning to USB-C transition there will be a lot of e-waste generated... unless the connector is identical
