To play another devil's advocate, shouldn't that also imply that IE10 users sending Do Not Track are in fact explicitly representing their desire not to be tracked? I mean by that same argument the user, by using Windows/IE10 did in fact choose the default settings of the browser, per the terms and conditions agreed to upon installing/purchasing Windows/IE.
