Re: Next 2 calls canceled (Oct 09 and Oct 16)

Matthias,

On option #1 - legal minds are stating this will not be possible.  While
the concepts of "all-or-nothing" and "tracking-walls" are still heavily
debated, I believe we'll need to develop a solution that supports a data
subject's ability to selective consent to some of the requested purposes
(versus all or none of them).

On option #2 - if we are required to use cookies to facilitate the consent
process then there is little to no utility in DNT.  Industry can just use
cookies for the entire process.  The motivation for leveraging DNT over
cookies is that these are held out under separate controls from cookies -
and hopefully avoid proactive blocking activities such as 3rd party cookie
blocking and Apple's ITP.  We're trying to do the right thing here so let's
not punish good actors in the fear of bad actors.

The discussion on fingerprinting in this context is a bit of a red herring
IMHO.  The number of legitimate purposes should be small (6 or less).  In
all cases there is a full record of the UGE registration so those misusing
this feature for illegitimate means can be quickly tracked (back to the
specific domain) and dealt with -- versus other forms of fingerprinting
which are often invisible to the browser.
