That makes the biggest song writers, novelists, screen writers trolls.
A fairly unknown Dolly Parton song became one of the biggest song of all times, thanks to Whitney Houston. Dolly made an estimated 20 million dollars for royalties for a song she hasn't touched since the 70s (which barely made a dent back then). what a troll
James Cameron had zero involvements with any of the terminator movies since 1992, but got millions of dollars in royalties for characters he last used in 1991. for all purposes he's a troll too.
And don't get me started with George Lucas, and dozens others who license rights for movies, characters and songs they created. They all haven't been 'using' their creations, yet somehow got royalties for them. How dare they! Trolls
All your examples are of people that actually created something that was later reused by somebody else.
Dolly Parton didn't write a vague description of an idea for a song that may use one or more of the notes A-G and then try to get money from a more successful artist decades later.
