Basically, he stepped back and took "WoW" out of his name so they can't sue over that. Apparently they're both just sitting and waiting.
Apparently Blizzard has a pretty convincing case against him. He's causing them financial harm because of users quitting the game.
That's a very invalid argument. Blizzard sells more copies of WoW because of Glider, look at it like this:
User buys WoW
User Glides
User pays for his (X) months
User gets banned
User buys WoW
User Glides
User pays again for (X) months
It's just an endless cycle, Blizzard may lose the $15 for the one month the new account gets for free, but they gain an additional $15 back from the cost of a new game ( $30 now right? )
