As far as I know, the new Creality K1 printer comes with a modified version of Klipper. Since Klipper is released under the GPLv3 license, Creality would be obliged to provide the source code as well, including all of their modifications. I could not find the source code online, so I asked the Creality support. I got a quite fast answer (next day):
I’m sorry, the source code of K1 is not open yet.
I was expecting something like this, still I replied stating once more that they are obliged to hand out the source code due to the license, but I still got this:

I presume, Creality has not received any special license, since to my knowledge Klipper is not dual licensed. To my knowledge, they have modified Klipper and added long-wanted support for the HX711 for bed leveling etc, so I really would like to have a look at this. What should we do now? Maybe Kevin or one of the other maintainers can say a word about this. I could try to get in contact with some people with experience how to act against GPL violations. Shall I try this?
