Yes yes i know most of the times editors exercise monopoly but i contribute sometimes if i can (usually fixing grammar, typos, minor errors etc.). My largest addition to an article has been the Plot section of this movie.

I had watched the film. The plot section was missing from wiki page likely because it was an unheard arthouse film so i took to adding the entire plot section. Happened sometime in 2022.
