The only sane thing to do in response to this is the same thing that SHOULD have been done when Paramount went all sue happy on folks making unofficial Star Trek stuff.
Creators should stop making things related to their works and consumers should stop consuming and giving Paramount money for the official works.
The lesson being if the rights holder for something wants to keep it all to themselves, let them, forget it exists and starve it out of profitable existence. Spend the time and money with content, creators, and consumers that don’t believe sucking up ever dime that’s not nailed down is, or should be, the ultimate goal.
