Check the original issue tracker or the early days of the mailing list to find hot debates as to what level of responsibility first parties ought to have. But we are not constitutional scholars so it is moot either way, yes? :-) It just seemed unfair to beat up on Walter when he wasn’t even wrong...

I agree, and (in TPE) the DNT signal is about tracking (collecting or
using data across multiple distinct contexts) whether or not the service
being used is a first party.  Hence, it matches how first party sites
like Pinterest and a few others have been interpreting the DNT signal
even without a standard.

Well, I'd say that Alice's consent applies to whatever Alice (when
properly informed) has consented.

If the page asked for consent for partners X and Z as linked to by Y! for
some reasonable length of time, then the only consent Alice has given is
for Y! -> X and Y! -> Z for the duration of time described.

If, however, the page asked Alice's consent for all links Y! -> B wherein
B is a certified member of Bob's Big Brother network and subject to a specific
edition of policies as published by BBB, and Alice gave that consent, then
why should Alice care whether the partners change, so long as they remain
within the scope of consent?  Keep in mind that it is the site having or
using the data (not the user and not the browser) which is responsible
for ensuring the data use/storage remains within the scope of consent.

I know some folks have argued that users cannot consent when they don't
know the legal identity of the business to which the information has been
provided.  I don't believe there is any rational basis for that opinion,
given how everyday users provide their own identity on every non-cash
purchase in the realm of retail and restaurant sales to whatever salesperson
they encounter, and rarely have any idea who employs the salesperson,
who owns that establishment, and to what extent legal entities might
be intertwined across multiple establishments.  I prefer to think that
their consent is limited to purpose, limited to some extent by industry
things like PCI credit card compliance, and limited overall by laws and
regulations.  Not by the user's ability to remember who owns what.

Cheers,
