I think for three reasons: 1. They handle a lot of mom-and-pop business with actual live people on the phones and web chat. 2. For the "you're a computer guy, right?" relatives of those mom-and-pop business owners GoDaddy is large enough that most hosting sites have instructions for it directly. 3. Changing registrars is a pain. I know that GoDaddy is going to stay around. I can't be so sure for smaller dedicated registrars or that Google won't decide to discontinue their registration service and force me to change down the line. My time is limited and the peace of mind that I won't have to change is worth a few dollars a year.
