Disagree. The spots on the leopard don't simply change and there's no such thing as "anonymous" to Facebook. That's antithesis to their business. This is purely a PR play.
By the way, we learned from the AOL data breach in 2006 that "anonymous" doesn't actually exist on the internet[1]. So let's not pretend Facebook is trying to do us all a great favor.
