I agree that it can be a bit of both sides here, however what are the practical ways to prevent that? If you give your kid an hour of iPad time a day or whatever, are you going to stand over their shoulder the whole time? Maybe you have the technical expertise to block certain websites on a case by case basis on your router, but that's not most people. Even then, as soon as they're not on your home network anymore, it's free game. Again, I'm not saying the proposed french way is perfect, or even good, i'm conflicted.
