It's cute how they think they can control every technology by controlling commercial sales. And this after 3D printing started as this huge RepRap movement where everybody and their friend built their 3D printer from online instructions and rollerblade bearings.
Up next: when buy a 3D printer kit, you have to agree to only flash the unmodified firmware on your Arduino, and not one of the forks from Github. And you are no longer allowed to create your own hardware at home, or tinker with electronics of any kind, or publish instruction how to make your own electronics. And after that, you now need to register yourself before you can use a debugger.
