We have had a similar discussion on Hacker News about a company that claims to be mechanically generating all possible arrangements of words of a certain length and copyrighting those, as well as all possible images of a certain size, and all possible musical melodies of a certain length, and so on. The reason this is not considered copyrightable is that there must be some evidence of creative effort. Owning an infinite number of monkeys and typewriters does not entitle you to copyright everything they generate.
