That's a whole new different level of f@*ked up sh$t right there. HG is basically sending a message to the fandom that they ( the fans) are no longer allowed to support robotech. This is proof people, HG is trying to kill this already in life-support franchise by alienating their fanbase.

From my understanding, HG will quickly lose their trademark once they no longer have the Macross license, since they can no longer do anything with the trademark without Macross merchandises, and the law doesn't allow anyone to illegally squatting on a trademark.
