Bambu Lab has just released a beta firmware for their 3D printers that includes DRM: https://blog.bambulab.com/firmware-update-introducing-new-authorization-control-system-2/. it removes the ability to control your printer over the network from anything but Bambu software.

Bambu claims that the negative response to their DRM is due to confusion, but nobody is confused. this new firmware doesn’t offer any security benefits; it has already been trivially broken. its only purpose is to be a DMCA hazard.
