not 100% sure, but i believe that there was a case against emulators and emulators won. I think it goes like this: As long as you own the legal copy of the game they cannot tell you how to play it. Thats why there is so many servers for other games like lineage2 and ragnarok has legal emulated servers as well as eqemu. Now, I'm aware that WoW won a case about Emus so i really dont know what to say, seems whoever has the most money wins. But EQ is dying they can only put up a fight for so long anyways. I havent read much the WoW case so I dont know the details.
