Re: Today's call: summary on user agent compliance

Hi Shane,

I want to reiterate what I said earlier on -- I understand there is 
already an agreement on defaults in the group, and it is not my 
intention to question that.

However, in this context, I'm not clear that where a server merely 
notifies the user they will ignore their DNT-1 signal, that this is 
sufficient to gain user consent for server tracking.

Let me explain. The basis for tracking under the current spec is that 
the server is gaining implicit, opt-out consent to track the user. The 
'opt-out' consent is mediated through the UA's browser mechanism. Now, 
if the server is saying 'I will ignore your DNT-1 because I deem it 
non-compliant', there is no longer an opt-out consent mechanism in place 
for the server to rely on.

Best,
Tamir

If the user doesn't feel comfortable with this outcome WHICH IS COMPLETELY TRANSPARENT, they can decide to keep consuming those free services with DNT not being honored, not access the free content from that particular site, or switch to a compliant UA so their DNT signal is honored while interacting with that site.  With transparent and clear messaging to the user, this places the power within the user's hands to decide how best to move forward.  I believe this is much better than the user being left in the dark, or alternately no publishers supporting DNT since they are forced to honor non-compliant signals.

I hope we can discuss and build support for a consensus on the proposal sent the other day by EFF/Mozilla and Jonathan.  Without meaningful collection and retention policy, we risk not having a spec that can receive the support from many stakeholders (esp civil society).  That is critical to the fate of the privacy and digital consumer protection debates, esp. both sides of the Atlantic.

>> Finally, I want to add that in my view and fairly quickly a site that doesn't honor DNT will not be considered "brand safe."  Responsible advertisers and brands concerned about their reputation will need to respect a robust DNT.  They will have to add DNT to the blacklist/whitelist systems in place.  It behooves us to continue to advance the process of ensuring monetization and privacy can thrive together in the digital economy.

But whether it is "compliant" to the DNT recommendation or not, is up to us as a working group. It is our task to discuss whether we want the spec to allow this cherry-picking. (Don't get me wrong, companies can stll do so. But will they be able to claim DNT compliance?).
