<i>- facebook gives trademark law preference over personal names (they may have been threatened to be sued, but then they should have simply stood up for their users).</i><p>Sued? For what? Under the Fair Facebook Vanity Names Act? There is no conceivable case Harman would have against FB for URLs on their own site!<p>FB might have a policy which would give companies priority. I think Twitter has been doing something similar when it reassigns celebrity names; in such cases the personal name of the original user is irrelevant as the decision is based upon what most people would expect from that name/what the company wants. Obviously, both Twitter and FB want to encourage companies and celebrities to endorse their service and offering them the names they want is a great way to get that endorsement.
