Anyone considered the monkeys didn't take the pictures and it was just set up to look like they did. Now they're kinda stuck because the only reason for the interest in the photos is because they were taken by monkeys, so they can't say they were actually taken by a person who holds the copyright to them because they will lose all there value

Based on the 3 photos in that article they all seem to be in focus and well composed which seems a bit unlikely, although not impossible.
