They're really not.Fans understand the dimensions of the box and know what's already in there. Fans are well aware that the box is full of tropes and clichés that people have grown sick of. Fans have spent time daydreaming of what could be outside of the box and contemplating what the box means. And fans can hire other writers too.
I don't trust fans to actually write a story that will "kill their darlings" to borrow an writer's phrase. If fans want what's outside the box then hiring someone unfamiliar should be a no-brainer.
Instead, we get lip service towards outside the box, self-praising, for copying elements and thinking popular acclaim is the same as something new.
