[Message part 1 (text/plain, inline)]

Guix,

This is not about Schrödinger's proprietary-until-proven-innocent 
binary.  The Updater includes at least two cores explicitly marked 
as non-free in Debian:

 libretro-genesisplusgx
 libretro-snes9x

Disabling the Updater seems like an open & shut case to me.

This is a shame, because I think these non-commercial clauses are 
silly and legally void.  Core authors can't place arbitrary 
restrictions on derivative works of a GPL3 project. 
Unfortunately, that obvious fact is for a court to point out, and 
until then we must act as if it makes any sense.

Arne, to address your last point first:

For the purpose of this (FSDG) discussion, that's exactly what 
‘advertised’ means.

I install Retroarch with Guix.  When I run Retroarch, it prods me 
to (literally) ‘use the Updater if available’.  When I do that, I 
can select from many cores, at least two of them non-free.

There is no way for me to know this important fact; I have to type 
the name of the core into a search engine and dig, possibly deep 
(not everyone knows the awesome power of a Debian copyright file 
:-).

You're not required to agree with any of the above, but Guix must.

Indeed, that would be against our stated goal of user freedom.

Comics aren't software so don't count, but take Linux-Libre: the 
fact that it refuses to load non-free firmware supplied by the 
user is a *bug*, and even upstream acknowleges this.  IceCat is 
another obvious example.

Same with Retroarch: if the user has a non-free core Guix's 
Retroarch must, IMPO, run it.

The difference is that at no point do Linux-Libre or IceCat ask me 
to ‘visit our cool firmware shoppe!’.  Indeed, the FF ‘Get New 
Add-ons’ button that directly advertises non-free software is 
disabled for that reason.

It's just as bad for the same reason.  Like proprietary licences, 
this one restricts redistribution *and* use of the software:

 “Permission to use, copy, modify and/or distribute Snes9x in 
 both binary
  and source form, for non-commercial purposes, is hereby granted 
  without
  fee […] Snes9x is freeware for PERSONAL USE only.”

That violates a fundamental software freedom (#0: the freedom to 
run the software as you wish, for any purpose).

Contrast this with the GPL, which places zero restrictions on use 
— I don't even have to share the software or my improvements with 
anyone!

I don't see any similarities.  With any GPL3 software, I am always 
allowed to copy the software and do with it what I want, no matter 
the underlying storage at some point in time.

Kind regards,

T (not a lawyer but talks to them at parties when no one else 
will) G-R
