Identification can be either fuzzed or resold to aggregators and become effectively useless.

There's precendent for the emission signal in Do Not Track, but I don't think the result is what you want.

I'm talking about a legal mechanism relevant for the sale of hardware devices. Do Not Track was useless, but GDPR was not.

But what of the billions of already existing non-compliance recording devices, plus the ability to easily roll your own without including an emitter?

Even if it was successfully implemented it wouldn't actually at all tell you whether you're being recorded or not. Then what's the point?

You don't get to put that genie back in the bottle. If you normalize tracking, by giving it even tacit approval, then any "tacked on" privacy laws or regulations simply become a cost of doing business.

The GDPR has serious teeth - by there are still a large number of companies that flaunt the regulations. Like OATH.

Anything the user says to try and opt-out will be used as nothing more than an identifier to continue to track them.

We've already seen all this play out in the websphere. We do not want this to happen the same way in the real world.
