The laws on liability do definitely differ. The situation is murky in many countries, but it's not in Germany, where operators of open wifi networks are clearly considered responsible for illegal activity that takes place on them: http://www.edri.org/edrigram/number8.10/wifi-case-germany-copyright-infringement http://www.edri.org/edrigram/number8.10/wifi-case-germany-co... In Denmark I believe there's no bright-line rule either way, but there is no automatic liability. In practice there haven't been high-profile rulings going against open network operators (at least, not yet) to scare people off. In Finland there is clear non-liability: http://boingboing.net/2012/05/14/finnish-court-open-wifi-owner.html http://boingboing.net/2012/05/14/finnish-court-open-wifi-own...
