From everything we’ve seen, Pawel’s code is a legal third-party tool that is covered under open source software licensing, and in no way has he “impersonated” Bambu Labs or presented as them at any point.

The name of the software literally has "BambuLabs" in it. Not picking sides, but that's pretty dumb.

Also cease and desist are "easy" to handle, just host your code on a European git hoster or host your own gitlab/codeberg. That USA law doesn't affect EU platforms.
