This is the emails between the YouTuber YGK3D and Anycubic, it seems like they won’t send 3D printers to reviewers who mention their GPL3 license violations.
tl;dr Anycubic uses open-source software for their firmware, but doesn’t make it public as per license agreement, and they don’t seem to be friendly to anyone who calls this out.

Chinese manufactures have been great for the hobby in the short term, but their absolute disregard for the movement’s values will be devastating in the long term.
I don’t buy 3d printers as I enjoy building and modding them, but if I ever bought one it would be a Prusa, nevermind performance or convenience.
Prusa’s are damn nice and as Open-Source as can be.
I just wish they weren’t 3/4x the price
They are no longer as open source as can be. The Buddy Board, Nextruder, their nozzles, all closed source.
WTF are you on about? Bearded men in sheds printing Magic the Gathering characters?
