I don't see the conflict. In fact, I think this case is ridiculous. A game should be fair? Ok, I am all for that. But simply building a tool that allows people to play unfairly does not constitute a crime or a civil offense. It might be immoral, but then my moral may be different of yours. Perhaps if you were in a tournament and someone uses a cheat, you could sue the cheater (and not the developer of the cheat, unless he happens to be the same person) for damages. But Blizzard? What damages did they had?
Besides, I don't see how he could have infringed their copyright since he doesn't distribute the game. If people cannot meddle with their own RAM because what's in there is protected by IP laws, we live in a very fucked world already.
I don't think you read the documents involved (including the stipulated damages issues already posted here).
Basically, Blizzard isn't just selling the software to users, but also the ongoing experience of the MMO which involves not only operating the servers and updating software, but also ensuring that the use of the software by legitimate customers isn't interrupted by illegitimate users.
A tremendous number of players find themselves disrupted by these Glider bots, and that's the damage.
