Some people fail to understand the built-in fun of leaving a story unfinished. Classic example: Gone With the Wind. (Yes, I know, the author's great-niece or someone did write a sequel, but NOT the original author). It's called, "Use your own imagination, people".

Unless I miss my guess, that's the bit with fanfic: "I don't own the rights, but choose to write or continue a story started by someone else myself. No expectations of either compensation or lawsuit for plagerizing expected". Isn't it?
