Comprehensive Response to Bambu's AGPLv3 Violations (Software Freedom Conservancy)
The Software Freedom Conservancy has responded to Bambu Lab's violations of the AGPLv3 regarding its 3D printers. Bambu Lab failed to provide the necessary source code and threatened a developer who created a compatible slicer. In response, the SFC has initiated the baltobu project to reverse-engineer Bambu's code and support the development of the Orca Slicer fork.

Opening excerpt (first ~120 words) tap to expand
The Software Freedom Conservancy (SFC) published a news item on May 18 about its response to violations of the AGPLv3 by Bambu Lab in its 3D printers. The company has not provided the source code to its modifications to a 3D "slicer" program that was released under the AGPLv3 and it has also threatened Paweł Jarczak who created a fork of a different slicer (Orca Slicer) released under AGPLv3 in order to interoperate with his Bambu printer. Based on that, the SFC has created the baltobu project aimed at reverse-engineering and reimplementing the Bambu code while also hosting the Orca Slicer fork. Bambu has behaved badly for years and made multiple, provably false public statements regarding the AGPLv3 and its requirements.
