Why have we not been given a definitive reason for > collecting/using UIDs? As far as I have understood, one needs to know the single user/device to be able to count on objects. If one doesn't know whether it is the same user or device, counting doesn't really work as it may e.g. be a bot. The second reason is that the audience measurers could make all of this up and just assert the result. So instead of having a burdensome inquiry with measures and beacons and things, one would just make things up. If the client has suspicions, they would say: No, we deleted all for privacy. Given that outreach determines ad-pricing, there needs to be a safeguard against manipulation. This safeguard is done with reproducible data sets so that one can prove the correctness of the results to the client. I think, on the long run, we can do better than we do now and without UIDs, but I personally believe this would overstretch the industry if written positivistically into a specification. The bar for implementing the TCS would become too high. But this is surely something we could imagine for an incremental improvement (version 1.1) for the Specification. --Rigo
