I like this proposal to add a "purpose" field to the cookie header. This could allow consent settings at the browser level, preventing all these pop-ups.
The problem isn't lack of a solution, we've had DNT for years. It's that the people who want to track you generally don't want to make it easy for you to opt out.
No, it's not legal. It's clearly not legal, it doesn't need a case. It's well established in the law as it was written.
It's just that the enforcement agencies are large, lazy and won't enforce anything. They don't even enforce when you can prove beyond a shadow of a doubt when and how the corporations have leaked your private information, let alone when their use of cookies is illegal.

Look at the difference between Germany and say Austria, for example. Or if you must compare two large countries Germany and France. There is quite a large gap between different countries.
