This article title is totally incorrect it misses a layer of logic. A better title would be: "Nathan Myhrvold's Cunning Plan to get royalties from 3D printer DRM software".
Nathan Myhrvold was issued a patent on 3D printer DRM software, good it will put a barrier in place for anyone wishing to make DRM software which fights piracy, so actually Nathan Myhrvold is helping 3D printer piracy.
