CBS went too far themselves. Instead of pulling the Axanar team aside and quietly going, look you guys are going too far too fast and we'd like you to ease up and not cross some of these lines, they went ahead and decided to go public with legal action.
Mark my words, if CBS wins the lawsuit, my fan fiction here and millions like it will be sued for all we are worth. Companies are cracking down on copyright infringement because even the smallest offense makes then millions hand over fist, because the courts almost always rule in their favor.
