Dear David, One doesn't have to look too far ahead to see practical problems with such an approach. For example, Yoyodyne Corporation a fictitious UA developer adapts Firefox and calls it Stalkerfree Browser, with all sorts of privacy settings on maximum, and advertises it as such. A user that chooses that UA does not have to be bothered with a pop-up explaining what he or she is about to do. For a browser like that DNT:1 is an expectation of the user already. Less fictitious, all the major UAs nowadays have a "privacy" or "incognito" mode. Again, it will be a user expectation that DNT:1 will be set, even when the normal setting is DNT:0. By invoking the privacy mode, the user expresses its intention to have DNT:1 set. In either case it is counterproductive to nag the user with questions and texts such as proposed. The furthest I am willing to go is that UAs should take reasonable steps to ensure that either DNT setting (1 or 0) are expressions of informed (non-)consent. Having non-normative texts in addition that explains that the best practice in this regard would be to have DNT:unset as a default while having user interact through dialog windows that explain that alleviated privacy settings may affect the browsing experience when changing this setting.
