Maybe, just maybe. The EU know more about this than you do?
Maybe they have thought 'look at this plethora of different leads that aren't interoperable between different manufacturers', and maybe they have looked at the landfill all of this produces?
I'd prefer a little bit of the stifled innovation you claim, (which isn't necessarily true), as opposed to all these different leads and adapters and the Apple tax you pay for lightning.
At some stage you would have had to bin lighting, after all we binned the old dock connector. Why not now for a better universal standard?
Bravo EU. BRAVO!!!
