While in theory it sounded good, the cookie warning law was so ridiculously useless, since most websites by default use cookies to manage your user session state, you were forced to implement it on everything, but not to do anything that would actually contribute to increased privacy for your users: by the time they clicked OK on that stupid cookie bar, they already had 15 tracking cookies installed and 0 ways to prevent that. It kind of seemed counter-productive to the whole thing.
So it's the "Do Not Track" header? But now it's legally enforceable?
I mean I wish they would just use the but I can only suspect that they are going to make their own new thing.
