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.

Prusa’s are damn nice and as Open-Source as can be.
I just wish they weren’t 3/4x the price
Prusa are Zionists. They recently partnered with Israeli company Fillament2. Also their printers no longer offer value over Bambu.
They are no longer as open source as can be. The Buddy Board, Nextruder, their nozzles, all closed source.
