The documentation is not up to date with the change. It still mentions MIT license in a few places:

https://github.com/Aircoookie/WLED-Docs/blob/main/docs/index.md?plain=1#L77-L91
https://github.com/Aircoookie/WLED-Docs/blob/main/docs/about/privacy-policy.md?plain=1#L23-L30

The license of this documentation itself is still MIT also, but I supposed that this might not need to be changed?
