Blizzard sues maker of WoW Glider

During the last week already Blizzard Entertainment and Vivendi Games filed against Michael Donnelly, creator of WoW Glider. WoW Glider is a so called Bot which acts for you and controls your character while you are away. Blizzard respectively Vivendi, who are known for banning thousands of players because of using such 3rd party software, accused Donelly of violating their rights associated with "World of Warcraft", of infringing copyrights owned by them, violating the DMCA and so on.
A fairly one-sided and biased presentation of what happened can be found at MarkeeDragon.
