Fanfiction writing becomes acceptable when creative spaces refuse to gatekeep or ensure study and research into the primary sources that inspired the IP that they love. Let's use Star Wars as an example.

Star Wars was inspired by:
>Lensmen
>Foundation
>Dune
>Barsoom
>Flash Gordon
>Kurosawa movies
>LOTR and The Hobbit
>Heavy Metal
>the sci-fi works of Harry Harrison
>Westerns
>WW2 movies
>Lawrence of Arabia
>Coppola's movies
>the works of Khalil Jibran and Carlos Castaneda
>Lucas' Methodist upbringing/The Bible
>Kirby's New Gods
>Metropolis
>Valerian
>Wagner's Ring Cycle
>Buddhism/Tao/Hindu religion and philosophy
>L Ron Hubbard's sci-fi
>Buck Rogers
>Tintin
>Shakespeare

So if you're a Star Wars fan (especially one that works for Lucasfilm), you should have a good grasp of all of this if you want to include something original that feels authentic to what Star Wars is. But we don't live in a culture that encourages us to learn more about what we consume.
