GoDaddy, world's largest domain registrar, has lost a bunch of it's happy customers because they supported SOPA ( Stop Online Piracy Act ). As a result, customers began to boycott GoDaddy and transferred their domains to other registrars like Namecheap and this took the shape of a movement on Reddit. We also saw lifehacker recommend people to Ditch Godaddy for better anti SOPA alternatives. Once GoDaddy saw the movement rising, they put on a blog post saying "GoDaddy doesn't support SOPA now", which made things even worse for them. 

This week, they lost around 72,000 domain registrations. At a yearly discounted rate of $6.99 (most registrations are higher), that’s over half a million dollars per year. It is apparently not enough for them to speak out against the bill.

This is a huge number but not sufficient enough for GoDaddy to withdraw it's official support for SOPA or to talk against it because GoDaddy has millions of domain registered under them.
