Blizzard's lawsuit against the Glider folks (who were trying to sell a bot that was used to play the game while /afk), has a new wrinkle in it. According to PC Gamer, an interest group called Public Knowledge (they're funded by a variety of creative arts foundations) has filed a brief in the case accusing Blizzard of overstepping their rights under copyright law. In the brief, and an accompanying blog post, they say that while what Glider is doing in-game may be wrong, it isn't actually copyright infringement, because the Glider software doesn't actually infringe on any copyrights that Blizzard holds. And they're worried that if Blizzard wins this case, it could set a precedent strongly in favor of copyright holders, to the point where any misuse of the software at all, from using bots to using the wrong name, would be interpreted instead as copyright infringement.
