Pirat_Nation 🔴(@Pirat_Nation):Josef Prusa of Prusa Research has raised serious concerns about Bambu Lab’s Bambu Studio slicer software. The program, a fork of the open-source PrusaSlicer, incorporates a closed-source networking plugin that Prusa describes as an unauditable “black box” downloaded from a CDN and capable of remote replacement. Prusa says this is dangerous because Chinese laws require companies to help their intelligence agencies and share encryption keys, and slicers handle sensitive 3D design files used in research labs, universities, and defense work. He also claims that Bambu Lab is breaking the open-source license rules by adding this closed part.
