I think that the backlash against their support was a lot more swift and severe than they'd anticipated. Their initially glib "lol, whatever" response was replaced by "oh god, please stop punching us in the quarterly financial report!" real fast.
I feel really bad for the customer service reps that have to do damage control on this. You know that they're going to be pulling overtime this Christmas weekend because their bosses screwed up. The guy I spoke to was professional, but you could tell that he'd made a lot of very similar calls today. He didn't even try to sell me, just sort of accepted it with a "Yup, I hear you, and we're sorry, let us know if we can do anything to get you back". Doesn't change my stance, though.
This is fantastic news on the anti-SOPA front, though. This has demonstrated that we, as consumers, can have an impact where it counts. This legislation is funded and driven by corporate interests, and demonstrating that we are able and willing to impact corporate bottom lines if they support legislation like this sends a very clear message. GoDaddy capitulating is a huge win, because it's the first stone to come out of the wall. Now that GoDaddy has demonstrated that they were taking too much damage to continue with their support of SOPA, it empowers people to exert similar pressure on other companies, and it demonstrates to those companies that there are enough angry people out there that you need to listen up and pay attention.
Update: A lot of people have asked who I switched to. I'm using Namecheap - http://namecheap.com. I guess my account has an affiliate link, as well - http://www.namecheap.com?aff=25763 if you want to use it. If you want another alternative to look at, Gandi's another I've heard very good things about, but they're more expensive. Either way, neither supports SOPA.
