Looks like something has happened, if you go there now, it goes to an IIS7 default page, so they've taken down the redirect, and whatever site they used to have up there. Probably got a lawyer's letter or something.
It's not actually EA that's got this domain, and trying to sabotage Activision, it's just some dude. According to the whois records, his name is Anthony Abraham. So it's not the two companies/CEO's battling it out, it's just some random guy trying to make a statement, and Activision is I think understandably upset about it
