We're not able to make it an "all-or-nothing" proposition legally. If that was possible we wouldn't need to have this conversation as then a single signal would cover our needs. OK. Kinda weird. The site may not do the quid-pro-quo (e.g. free access) unless you consent to it all. So ‘granular consent’ as I wrote below, and possibly ‘changing purposes over time’ are both issues. It’s easy for the site to talk back to itself; cookies, or even as I suggested using the DNT-extension. That covers the web-wide exception, and the site itself for site-specific. How do you think a site should convey to the ads and its 3rd-parties, for site-specific exceptions, which purposes they have consent for? “This user agreed to a non-vegetarian meal” “This user agreed to wearing synthetic fibers during the night-time” and so on? > > - Shane > > On Thu, Oct 12, 2017 at 11:33 PM, David Singer <singer@mac.com> wrote: > > > > On Oct 13, 2017, at 0:20 , Shane M Wiley <wileys@oath.com> wrote: > > > > I believe this is an over simplification of the issue. If we want DNT to meet the most basic needs of even small publishers that means they will need to support at least one ad tech partner (assuming the goal of the group is still to meet the original target of the standard). Even the most basic ad tech partner will participate in at least two distinct purposes which lawyers are expressing need to be consented to separately: interest-based advertising and cross-device mapping (all ad ecosystem participants support these two common approaches in the EU marketplace today). If the DNT standard is unable to support even the most basic consent scenario then there will likely be zero adoption - at least for the most common use case and original target of the standard. There may still be hyper edge cases where a singular purpose consent will cover all needed business cases. > > Shane > > I think I am confused. > > When consent is requested, the site manages the UI.
