If it's really going to be that simple to opt out of the survey, this shouldn't be too controversial. I've never been put out as a result of anything Blizzard's done, so I'm going to be a naive, ignorant soul.
Hey Blizzard! I have a Duron 750, 256 RAM, running winxp with a geforce 2 gts and a soundblaster live.
How, exactly, is letting Blizzard know this a problem?
Announcing this is probably just a CYA routine. On the Battle.net forums, Bill Roper can't take a piss without someone complaining about it.
