A comprehensive apology, admitting responsibility and reason, has been posted on the battle.net forums, authored by Blizzard Entertainment president Mike Morhaine.
To everyone who has signed and spread the word about this petition, I cannot thank you all enough. We have made a difference, and hopefully Blizzard knows now that their customer and fan base does NOT accept homophobia as a joke.
Stay strong, and keep fighting hate speech as you encounter it. Each of you has helped make the gaming world a safer place.
