While I think there's very little chance for the author to overturn this decision, and thus agree with you that he should just move on, you should have a look at the amount of features this small project offers. I don't think this could be considered "trademark squatting", there's a real effort put in that project, and for many years.

Perhaps I have the wrong idea of what it means to do trademark squatting, or did I misunderstand your point?
