If we go by the history of such anonymization attempts (AOL, Netflix) it is only a matter of time that someone figures out how to get PII from this data.
I think the title is misleading for the purposes of catching people's attention. The data is not available to download, and is in aggregate form. The AOL data was not in aggregate form, so it was possible to get personalized details.
They probably constructed a simple decision tree aggregate which is probably less than 10kb of data. I doubt anyone could extrapolate 10kb data into personalized details of an individual.
