Haven't these (A)GPL violations been there for most of the company's history? It's the context around them that changed.

While the ecosystem was open few people cared about the network plugin, and apart from that plugin the Bambu Studio slicer is open source. Similarly there was little interest in calling out the suspected violation of their online slicer - it's probably just a headless variant of Bambu Studio. But when Bambu started closing their ecosystem and claiming that user agent headers are DRM everyone got justifiably upset, and this is a just outlet for that

It's a shame because the Bambu product line is genuinely first class. They don't need to play these games to compete, and could have won a lot of genuine good will by giving a little back to the community.

it's hard to convince people to past over bambu when the alternative is either: Crappier (Ender, Creality), or much more expensive (Prusa).

Bambu and Prusa are both engaged in harm.

But Prusa is only engaged in self-harm.
