FWIW, no need to be angry with them. The reason everyone with a trademark would react exactly the same way is because they have to, by law. If they don't, the court will argue that they haven't protected their trademark and they will loose it. Yes, this happens in real life.
Thank you very much. Perhaps I was wrong. This requirement seems to present an ongoing responsibility/burden for the trademark holder, so it makes no sense for anyone to do it.
Does that mean places that explicitly allow "fan fiction" derivative works that use the trademark, are placing themselves at risk of losing ownership of that trademark?
If so, that's very disappointing, as it would seem to be suppressing the ability of authors/creators to be generous with their creations.
