They might be cheap, but they are far from easy, I would actually qualify it as the most painful purchase process I've ever experienced (my former employer had domains there). And my political beliefs had nothing to do here, technological beliefs at most.
Anyway, Godaddy is where I would expect my father to buy a domain, not someone at HN. Hence my surprise. But turns out the op didn't register the domain himself, he was just pointing it out.
