Actually, I found Steyn’s column tame, almost mild. For the most part, Steyn is commenting on an article appearing in http://www.openmarket.org/2012/07/13/the-other-scandal-in-unhappy-valley/
Exactly, for some reason, I guess deep pockets, these guys are going after National Review and Steyn. They will learn the lesson of going after people who own servers, ie the modern equivalent to buy ink by the barrel.
