To all those pontificating about EU 'tyranny' or 'overreach': Let's not forget that the EU is a collection of democracies (plus one or two quasi-democracies like Turkey) and, as such, is subject to the will of its citizens. From everything I've read, public sentiment in the EU is in favor of this. Plus it's good policy, since it's in the public interest: It provides direct benefit to consumers, and general benefit to the environment. So the EU passing this legislation is just good government, and is how democracies are supposed to work. It would have been arrogant for the EU to ignore the will of its citizens and not do this.
The issue is how will they handle this when the next better cable comes along. We know USB is good because the marketplace decided it. So when industry comes up with the next better thing, there needs to be a provision to allow that to be tested in the market (a pilot program) to see how well it actually works. Then a consensus needs to be reached. This will require some very smart thinking, and often neither government nor industry is smart enough, and insightful enough, to get these things right.
