what bothers me is that most websites just show the warning but sends you the cookie anyway while they are mandated to wait till you agree to do that, and basically there is no enforcement so even if I were upset about a site tracking me without consent, I cannot report it and no penalty will actually ever happen to people in violation of this law.
anyway, I think this is mostly a social and educational failure and shows how much more we need to do before we actually own our own hardware instead of relying on the god will of third parties, which never actually works.
moreover this should have been fixed at browser level, and it already was. anyone caring for privacy already had configured the browser for this stuff; at most people just needed more awareness on what was already available in term of privacy controlling extensions
instead we got retarded regulations which explicitly exclude session, authentication and social cookies so basically does nothing about the real issue - 'oh this is not google analytics, it's google plus tracking you - wink wink' - and data mining proceeds as usual.
