The piece covers state proposals to force 3D printers or slicers to block files that might make gun parts, while critics argue the tech is easy to bypass, would sweep up legitimate.

@Quelly the privacy piece matters because slicers would end up inspecting a lot of normal hobby and repair files, and the tradeoff is you still mostly punish stock firmware users while anyone determined just shifts to offline or modified tools.
