Ah, true. I didn't know about Grayjay, though. It doesn't seem to mention this on their website or GitLab, but I can see that the license is proprietary. Ok, their license does use the words "open source". You are not even allowed to edit the code! Crazy and a huge shame for something coming from people in the right to repair movement. Software freedom should be one of their goals. But I guess they think you should be able to control hardware, but not software.
