I think the special thing about this one is that it's open source and you can build it from common components, which makes sense. You literally just need a stepper or servo motor with the correct algorithm and a few bits & pieces to apply that motor to the dial.
It should be easy enough to build this for no more than a hundred bucks, maybe less if you can get cheap parts or you're building more than one. It's actually less complex than a basic 3d printer.
The expensive part comes from the low volume production and the professional customers. Plus the software is probably proprietary. It takes expertise and to make a business out of that means high individual prices.
So it's really a perfect candidate for open sourcing.
