The Mattel vs. cphack case is becoming more and more byzantine. It turns out that the GPL may not protect people redistributing cphack if the authors didn’t assign their rights to the software to the FSF in writing. It looks like this one is going to have to be hashed out through litigation. Of course, Mattel is clearly playing the part of the evil jerk here, they should just give up and accept the fact that people have a right to know which sites their product filters. Declan McCullagh has a Wired News story that attempts to provide the details.
