I guess I can see both sides here. Yes, CBS is being asshole-ish about this whole thing. But at the same time, it is their property, and if they don't want fan made projects out there, it is their prerogative. And I know this is just a simulation, and a non-profit one at that, so they are really being dicks about their stance, but again, they own it, so they do get final say. We don't have to like it.
I've sort of been at odds with everything in the "fan fiction" realm for a while now. About a year or so back, I saw a video from a YouTuber who writes fan fic and does videos for others in the community, and she went on a long rant about how she would never read a book by Anne Rice because of Anne's stance on fan fic, and this particular young lady was afraid that she might enjoy the books and be tempted to write fan fic, which Anne hates. Um, to me that's a pretty stupid reason to not read a book or series of books. There are lots of books I love, and have never sat and thought "I should avoid this, lest I be tempted to write a fan fiction based upon it". I get the idea behind doing it, and have seen some fan made movies based on popular films that were, at times, better than what was being put out by the studios. I dunno, maybe I'm just out of touch.
