Cybersquatting laws seem like such bull to me. If Activision really wants it, they'll just get it, because that's how the Anticybersquatting Act works. It's pretty unfair, because it basically says: "yes, that domain is yours, but this guy over here has a better reason to use it, so it's not yours anymore. Ahahahah, go away, sad little man."
That said, I appreciate what they're doing, and that they're doing it in a humorous way, and likely for a lark, not for any serious reason cybersquatting-esque reason.
