I'm not giving a legal opinion, but some say that

"Consent must be freely given, specific, informed and unambiguous."

So a question remains, if you give someone the option to decline to be tracked, is that enough? Or do you need actual consent?

The EU website is doing the tracking with option not to be. Other experts say you really should have consent first before doing any tracking.

Anyways, not giving my opinion on which is right, just that there are different views, and even EU does it in ways I think that folks here do not understand.

The one thing, the EU sites are extremely CLEAR about things, I do like that.
