I don't know, releasing a sellable product from an algorithm is a huge undertaking, probably harder and definitely less interesting than developing the algorithm itself. This was just a three-month work project by some smart students, who afterwards got lucrative jobs working in industry.
In more practical terms, people who actually listen to vinyls get to appreciate the "cracks", and they wouldn't really see the point in such a product. Major studios have surely developed similar tools internally. The method is probably a scientific curiosity, mostly of educative interest, like observing the helium in the sun atmosphere with a hand-made spectometer built with an old CD and a cereal box.
