I don't think Doz erred. They went out, probably paid 5 digits for the doz.com domain name months ago, but didn't register it as a trademark. And then seomoz goes and rebrands last week and they are caught off guard. If moz wants the doz.com domain, they should pay for it. Why should doz just give it up over such a weak claim?
