Right; the source is downloaded from commondatastorage.googleapis.com
but that is a technicality. What I'm saying is that the recipe should
be updated to cause it to download an already-cleaned up version
directly from Guix (it could be hosted somewhere on gnu.org for example
but exactly where can be up for negotiation) and that this excuse of
"they're getting it elsewhere" shouldn't be usable as an excuse to
sidestep the FSDG. It's still causing the user to download the software
due to the recipes provided by Guix.

It's still being downloaded into their computer and then being cleaned
up after the fact. If there weren't freedom problems with it there
wouldn't be a need for a clean-up program (ungoogled-chromium in this
case) to be running -- as a process on the user's computer -- to do
this.

And in https://www.gnu.org/distros/free-system-distribution-guidelines.
html we have:

"For instance, a free system distribution must not contain browsers that 
implement EME, the browser functionality designed to load DRM modules."

So that should make it quite clear.
