Good luck enforcing that if they ever tried (not only because of the obvious jurisdictional issues involved) - and the longer they let blatant "infringement" occur without pursing it the less likely they'll be able to maintain it.

There's a reason why companies send around takedown notices and sue people for using their trademark even if they aren't actually being pricks - you have to protect your trademark. (Otherwise it looks like a case of "we're unfairly picking on this one guy even though we let everyone else get away with doing the same thing).
