Otherwise, why contribute to the story at all, if you're just going to ignore what came before?
It is a strawman. No one said anything about not respecting what came before. Taking the story in your own direction (within established plotlines, characters, style, genre, universe...) is not the same as ignoring what came before in the story. Not wishing to follow railroad options from the other author is a very different thing. Sure, the owner of the story is the king. If they have a railroad in mind - it is their absolute right. But this is the opposite of promoting creativity and encouraging other people to add. There is nothing fun in the "Do you do A, B or C?" when you have an idea for D. Nothing.
