Doesn't rejecting 3rd-party cookies (or more accurately, not sending
them back to anyone) solve that problem? I had always thought that any
system or configuration with "privacy > 0" in the list-of-design-goals
would do that. It seems more effective than the do-not-track header
(that I gather is widely ignored by people in the tracking (ad) business).

plugged in on any individual wire was guesswork. It was even conceivable
that they watched everybody all the time." -- George Orwell, "1984"
