It's really simple - it specifically refers to "prepared spells" and oracles don't don't have those. It's not a restrictive interpretation, its what the rules actually say.
You would need to change the actual text of the rules to do what you want. In a home game, the DM can easily do that. In Pathfinder Organized Play, they can't do case by case rulings because they are dealing with players from all over the world.
