Isn't the argument that the act of selecting the right quote is the real work - and the work the copier avoided in the act of copying?
You could argue that all the words are already in the dictionary - so none of them are new, you are just quoting from the dictionary in a particular order......
The reason you have people, rather than computers interpreting the law, is you can make judgements that make sense. Fundamentally these laws are there to protect work being unfairly ripped off.
What was clearly done in this case was a rip-off which damaged the original creator - everything else is dancing on the head of a pin.
