It used to be the case in Europe that you couldn't use a washing machine made for Sweden in Norway. Everything was different. Every country had its own standards too, which had to certify your products. It was openly for protectionistic reasons.

EU got rid of that. It only makes sense that they don't let private companies start all that crap up again. If states don't get to use artificial technological barriers as protectionism, certainly Apple shouldn't be allowed to either.
