As much as I dislike GoDaddy, and am glad I've switched away, I can't see how this kind of attack can possibly result in progress towards Anonymous's goals. It serves only to make them seem like radical thugs, far from being aggressive protectors of internet freedom.
That's kinda the point though isn't it? Why is anyone still using GoDaddy after SOPA / elephant killing / earlier outages / etc? For me at least, there's no excuse in supporting this company with my business.
I'd switched half of my domains to Namecheap. I was waiting to migrate the other half. I do not support them, but I had hired their service before SOPA and I just didn't want to pay twice.
