By default it is, but there are many non-free channels you can use to add the OG Linux kernel to your Guix install as well as nonfree drivers. A famous one is nonguix, which i also use in my config. They also make custom ISOs with the Linux kernel, which helps some hardware indeed. So the libre only policy is a non issue if you read into it a little, but unfortunately most people stay at surface level


Just move to Guix already 😊
