An anonymous reader writes How to make politicians really understand the dangers of mass digital surveillance and the importance of information security? Gustav Nipe, the 26-year old president of the Swedish Pirate Party's youth wing, tried to do it by setting up an open Wi-Fi network at the Society and Defence National Conference held in Sälen, Sweden, and collecting and analyzing the metadata of conference attendees who connected to it. Nipe set up an open wireless Internet access point named "Open Guest" and over 100 delegates used this particular unsecured Wi-Fi network to go online. The collected metadata showed that, among other sites, they visited those of daily Swedish newspaper Aftonbladet, Swedish private ads website Blocket, eBay, and tourism sites. "This was during the day when I suppose they were being paid to be at the conference working," Nipe noted for The Local.
