Bambu Lab faces criticism for allegedly abusing open source social contract after threatening legal action against an OrcaSlicer fork developer. The dispute centers on OrcaSlicer-bambulab, which allowed printer features without routing through Bambu's cloud servers. This comes after Bambu shifted to cloud-connected printers as default, forcing users to firewall devices or use older firmware to maintain control of their hardware.

The technical conflict involves AGPLv3 licensing. The fork developer claims they used Bambu Studio's upstream code verbatim while Bambu alleges "impersonation attack" through falsified metadata. Louis Rossmann pledged $10,000 to support the developer's legal defense. The irony is thick—Bambu itself previously caused user telemetry to hit Prusa's servers without facing similar consequences, highlighting inconsistent enforcement of open source principles.

This dispute reveals deeper tensions between hardware companies and open source communities. Rather than addressing infrastructure concerns collaboratively, Bambu targeted a single developer. The author recommends avoiding Bambu products entirely, suggesting companies that respect user ownership of hardware. The case sets a concerning precedent for how commercial entities interact with open source derivatives in consumer hardware ecosystems.
