Imagine all the incredible fan works that could spark careers and businesses if e.g. the original star wars trilogy were public domain, or how many indie dev studios could get started by riffing on pokemon. But alas, fans of both franchises continue to make works but can't profit from them and need to pray that Disney and Nintendo won't send lawyers after them if they get popular
Fan works of Star Wars have long been as good or better than the official releases. The world would be a much richer place if anyone was free to create whatever they wanted.
