Wikipedia Life and Death

There was a fascinating article in the New York Times today about the power of Wikipedia in a life or death situation. A NY Times news reporter and his translator were taken hostage by the Taliban and the editor at the NY Times didn't want this information to go public in order to safeguard the lives of the two men. How did the editors at Wikipedia keep this information private and did taking information off the site conflict with its open access philosophy? http://www.nytimes.com/2009/06/29/technology/internet/29wiki.html?_r=1&ref=business
