At some point we need to draw line in the sand to call out bad actors as "bad".  We've agreed users should expressly activate DNT on their own (expect in cases where the act of installing a CLEARLY privacy protective product is their goal).  If bad actor UAs cross that line (i.e. IE10 :-) ), then Servers should have the flexibility to respond appropriately.  This will make the situation very transparent to users (response header/well known URI) and allow them to exercise choices the Server provides (list of supported UAs, for example).

Your belief that ALL Servers should honor the ALL DNT:1 header requests, while very simple, is the basis for a pure opt-in world which all sides had previously agreed is the not the appropriate outcome for the Internet.  Is the CDT taking a different stance on this topic?

Thank you,

Even if a user does not *choose* a browser because DNT is enabled by 
default, the user may well be *aware* that DNT is turned on by default.  
Or the user might go to turn on DNT and notice that it was already 
checked.  The ad network is never going to know what the user's 
knowledge and intent is in any case.  For this reason, I believe ad 
networks should respect the signal regardless.  Assuming that the group 
wants to ensure that users knowingly choose to transmit the DNT signal, 
wouldn't it make more sense to put the burden on the implementing 
browsers?  This would give the browsers an affirmative responsibility to 
conform to the specifications in the standard and would prevent a 
situation where all third parties are making subjective determinations 
about user intent and the legitimacy of any particular UI.
