The right to privacy is unimplementable. It basically requires hiding the truth on a massive individualized scale, and cannot be done.
If one were to attempt hiding one or a few particular truths, it might be successful for a short while, but it would be like the Soviets airbrushing former leaders out of pictures. The truth will resurface sooner or later.
And as soon as you mandate the right to be forgotten, every punk and his dog will want to protect their privacy too -- why should it be reserved only for the rich and powerful? Not only will the resultant holes in truth became ever more blatant, but the only way to hide the truth is manpower intensive, just like airbrushing people out of all those pictures. You can't automate it -- not only would it miss indirect references and intentional subterfuge, it will erase false positives and raise the ire of its false victims.
I am watching this EU court ruling with a metric boatload of popcorn. Most legislation is pretty clueless when it comes to unintended consequences, btu this one is spectacularly so.
