I understand needing to protect your IP, in some sense, but what I'm getting at is that when a fan game is made, it is a homage to a beloved franchise that fosters love for the IP. If you were a smart company, you would foster this love for your franchise, to entrench the fans you already have, and to gather more fans because you are seen as the company that "does no wrong", which in turn also increases your profits. Imagine if instead of taking these love letters to your franchise down (which makes you look like an absolute fucking ass to most), you made a feature of it on an official channel. Look at Scott Cawthon and his Five Nights at Freddy's franchise. He encourages people to make fan games using his original ideas and that encourages people to not only love his own games, but to go out and start developing their own little games that include ideas that Scott may not have even thought about including before. I guess what I'm trying to say is that there is a good way of protecting your IP by taking down blatant rip offs of your game that want to steal money from your fans, and cause confusion to new fans. Then there is the bad way, which is taking down these passionate love letters to your franchise that encourage others to look at the original source and see why they even decided to take the time to create the fan game in the first place. IF the fan game is trying to monetize, then by all means, send a warning. Tell them to not monetize it, and they are free to continue. If they continue, Cease and Desist. Hopefully that makes sense.
