I repeat my concern (and will not repeat my arguments) against an exception for audience measurement for non panel users. DNT must be meaningful, even for aggregate reportings. The fact that the data is used for calibration exceeds the purpose of aggregation IMHO. Data from a larger audience, not being panel members, must not be used in a feedbackloop, ie for calibration.
