But if you dare to use the non-free channel, you get shouted at if you try to ask for any form of assistance, even for problems entirely unrelated to it. Speaking from experience.
wat? I'm using channels providing nonfree software. Even "worse", I contribute to those channels.
These channels are not for #guix, because the discussion there is meant for the base channel provided and maintained by the Guix project; but on #nonguix, or #guix-hpc (for e.g. guix-science, guix-science-nonfree, etc) you get to discuss these channels all you want and get help.
