Earlier quoted context omitted.
The EU just should have said "if you don't respect DNT, go directly to jail and don't pass Go".
How would not respecting DNT have been proven? The rub here is that everyone wanted to ignore DNT, because it made them lots and lots of money.
I think those pop ups are the worst thing that ever happened to the web because they eliminated the moral authority that anyone had to say “it is user hostile to use pop ups”. Once the EU made it appear “required” and even “laudable” or “prosocial” there was no basis to say “you shouldn’t put this other popup in that will make users feel harassed”.
So now we get pages where the popups get in the way of the other popups.
