Agreed, Facebook definitely has the ability to provide timestamped interaction events as part of "Download my Data". Maybe legislation will force them to provide that information at some point, but that won't really have any effect on user privacy. The hearing seems to want to get more to the heart of the issue, but is inept to do so. The stored data isn't the concern, it's the predictive capability of models built on it. The decision of a predictive model isn't any more traceable to a single piece of data than a brick in a road is traceable to a given taxpayer, which is what I was trying to get at with the analogy. After reading some of the transcript, the special masters seem very on the ball, and it's more the spin of the article I take issue with.
