Request for Guidance on GPL Compliance and Source Code Release – YUNZII Tri-Mode Boards

Issue Description

Hello QMK Team,

This is Kris from YUNZII, the keyboard manufacturer. We recently noticed that YUNZII was listed in your License Violations section regarding our tri-mode keyboards based on QMK firmware. We sincerely appreciate the QMK project and the community for maintaining such an open and innovative platform, and we would like to address this issue properly.

Our intention has never been to violate the GPL or QMK’s licensing terms. The tri-mode models in question use a proprietary wireless driver, which has created uncertainty on how to properly handle source release while protecting necessary IP. However, we fully understand the importance of open-source compliance and wish to provide the appropriate source code or acceptable alternative in accordance with QMK’s requirements.

We kindly request your guidance on the following:

1. What specific parts of the firmware or codebase must be made public to achieve full GPL compliance for tri-mode boards?
2. Is it acceptable to release partial code or interface documentation where proprietary wireless libraries cannot be shared?
3. How should we formally submit the source code or evidence of compliance for your review?

We are fully committed to resolving this matter and ensuring that YUNZII’s QMK-based products meet the project’s licensing expectations. Please advise us on the next steps, or let us know if we should reach out to a specific member of the QMK compliance or legal team.

Thank you very much for your time and assistance. We look forward to your reply and to making YUNZII fully compliant with the GPL and QMK policies.

Warm regards, Kris YUNZII Keyboard
