Maybe John has different values from Sam in the fanfiction. Their personalities or goals might be so different that John can't develop feelings of love for Sam.

One reason could be that the fanfiction writer is trying to show Bella's growth in a different way. By not having her love Edward, it allows for a different exploration of her character.

Also, it might be a reaction to the over - popularity of the Bella - Edward relationship in the original, and the writer wants to break away from it.
