Michael Arrington and TechCrunch have lost a libel case brought against them in the U.K. by a former business associate, Sam Sethi.
The key word in that last sentence is "U.K.". Libel cases are very difficult to fight in Britain and Arrington chose not to fight this one, resulting in a default judgment. British libel law is so plaintiff-friendly that it attracts "forum shoppers" who would be unable to win elsewhere. New York even has a law on the books to exclude even the possibility of U.K. libel judgments being collected locally.
Assuming TechCrunch has no assets to plunder in the U.K., the likely worst result for Arrington is being unable to visit the country without great inconvenience. (Update: This is not legal advice!)
In other words, the result doesn't say anything meaningful about any of the parties.
