I do agree that legislating technology this way is a big mistake on EU's part. This is basically South Korea's ActiveX law all over again, and like South Korea, the EU will eventually be left behind.
Nothing prevailed. Apple and Google dictated the API and the EU countries submitted, because they did not have time to enforce their will.
It is not Apple's, Google's, or America's fault that the EU has become so little innovative, rather hostile towards software developers and entrepreneurs, that they have no power in the digital world. And for the EU it is easier to blame american companies, instead of admitting failure and working towards creating an more enterprise-friendly hub in Europe.
I mean, as others have noted, why isn't the EU regulating the other side of the connector? Why are there 3+ power plugs in the EU? Shouldn't this be regulated first, if the EU's argument of reducing electronic waste be considered? No, those aren't created by american companies.
I'm sick of the EU, its constant attempts to circumvent privacy (such as the current legislation of ending end to end encryption for chats), while obviously lacking in the democracy department (why is the comission not elected?).
