If I read correctly, Clément just points out inaccuracies of the
David's answer [0]:

Correct, even if Guix tools is vague. Is "guix repl" a Guix tools? :-)

Incorrect, as Clément shows. And it is not a bug of the very
particular zpaq package, but a general feature of how Guix works.

We all agree on that. I guess.


In the initial Raghav's message, it seems that the argument is:
because Guix downloads non-free code in order to install free
software, then Guix does not follow the FSDG. This argument misreads
the current FSDG. For example, any GNU/linux distribution needs to
download non-free blobs and then removes them. Even, the FSDG webpage
[1] points to scripts [2] that remove these non-free blobs. The
keyword in the FSDG is "installable" and nothing is said about
"download", from my understanding.

I have not found neither.

However, from my perspective, all this seems more a troll than a real issue. :-)
