Apparently THE LAW can force companies to put up these annoying popups. Couldn't THE LAW force companies to respect Do Not Track?
Yes, yes, I know, smaller sites will not give a fuck.
But I bet Google, FB and other ones will. Which is why they fight against this so hard. Just try enabling Do Not Track in Chrome and watch the scary dialogs you need to go through which will make regular people think it's a dangerous thing to do.
