I think this blog post, and some of the facts that seem to be missing from it (as Andrew outlined above), shows that doz.com is trying to get people on their side without being entirely transparent. Which is a shame. Their argument dilutes when the moz.com people can come out with significant corrections to the facts.

That said, come on - moz.com (which you JUST changed to) and doz.com? I think you had other options than the "we're going to cancel your trademark" route.
