Oh, man, another missed opportunity to make the average Joe Six-Pack become aware of data aggregation and privacy violations. If the researcher had downloaded the 2TB of data and published it as a torrent, then laymen might care. When someone can query the list and see his own personal information being broadcast, they will understand. When they realize that anyone can look up the address, phone, and all sorts of other info about their wife, husband, girlfriend, boyfriend, boss, children, or neighbor, they might get an inkling that privacy isn't such a stupid thing to worry about.
I realize that we all suffer if it gets made into a torrent, but sometimes pain is necessary to get action.
Within a week, this whole thing will be forgotten and nothing will have changed because privacy is too abstract for most people -- they need to see the personal information that's being collected. The researcher acted properly, but going full Snowden would have had much greater impact on getting better privacy-preserving laws and technology.
