The article says he claims that he sometimes buys domains via GoDaddy. Why would he use GoDaddy since he can get them from cheaper (and more-ethical) domain name registrars than GoDaddy?
Ok, then I guess he just doesn't care that he's supporting an ethically-challenged company that has supported SOPA, etc.. but that's not too surprising.. giving what he does for a living :).
If you're only buying bulk domains from them, you're not really supporting their business very much.
