Mozilla's title, "A free and open internet shouldn't come at the expense of privacy", is very misleading about the content of the article. In plain speech, the article's about Mozilla looking for new ways to deliver ads in web browsers. Maybe this is a suitable place for mods to override the original title and write a non-deceptive one.
edit: Here's a few other threads on the same topic (of Mozilla's advocacy of a "privacy-preserving attribution", or "interoperable private attribution", of browser ads):
It is a lie on part of Mozilla. A logic that only makes sense with a lot of false premises, like the necessity and inevitably of surveillance advertising. A simple legislative change and all that would be illegal without it hitting the economy at all with exception of some parts of the advertising industry.
I don't know what changed for Mozilla, but this doesn't look like a way into the future.
Or maybe they want to go that way, but they then should release Firefox/Thunderbird from ambitions like these. These project had other goals than what Mozilla today espouses.
