I think we may be talking past each other.  What I'm trying to do is
distinguish between the use of previously collected data for
customization, on the one hand, from the collection of browsing behavioral
data, on the other hand.  What I'm suggesting is that it is possible for a
party to customize without collecting future behavioral data for
non-permitted uses and that we should recognize that distinction in the
spec -- and I think in large part you're both talking about the data
collection, not the use for customization.

Mike raises a separate point, which is that using first-party data for
customization (again, in the absence of data collection for non-permitted
uses) could cause people to "assume their wishes are being ignored," which
of course would not be the case for a company honoring the standard.  This
seems like more of a business issue than a technical or policy one.  If we
are concerned about collecting behavioral data, then companies who purport
to comply with the standard should not collect that data in ways that are
not permitted.  It certainly may be a good practice for companies to go
further and do other things to signal their compliance -- such as
providing a visible "DNT is on" indicator, etc. -- but these are things
that companies should be free to do or not do to promote positive
relationships with their users, not by a mandate in a specification.

I agree that Facebook, as a specific example, may be in a good position to
get consent from users -- but of course we can't write a standard for one
company specifically.  As a general matter, if we're concerned about data
collection on a per-network interaction basis, it seems excessive to write
a standard that retroactively restricts other data that was collected
directly from a user when DNT restrictions were not in place.

Also, Walter's note seems to imply that Facebook is building behavioral
advertising profiles using impression data from the Like button and that
this is happening without people's knowledge today.  I'm not sure what the
basis for this is, since our practice is to deidentify/delete plugin
impression data on a regular basis, whether or not DNT is enabled.
