This is good news (ok, not for Halderman but for the law). SunnComm says it is suing Alex Halderman (Ed Felten’s student) because he posted a paper pointing out the weaknesses in SunnComm’s copy-protection software. I’m sure there will be a world of legal support to help Halderman establish what should be an obvious point: tell the truth is not yet a crime, and (fortunately for most professors) writing even wrong papers is not either.
UPDATE: Oh well. Looks like SunnComm has come to its senses. No lawsuit after all.
