What a word salad. How do you know this won’t happen to GUIX, oybissue NIX has is it got popular really fast for some reason.
GUIX is a GNU Project. You know, Stallman et. al, the guy behind the FSF, or well… the GPL itself (GNU General Public License). If it happens with GUIX, Stallman would be the biggest troll in existence, and we’d have much larger problems to discuss about open source as a whole.
Like someone else already wrote : GUIX is a GNU Project. If you look how very long it took for Debian to include non-free firmware with the installer (Since Debian Bookworm) one may start to appreciate the difference between free software and open source.
I’ll be that guy pointing out at semantics - “open-source”, in the widely used OSI definition of the term is actually equal to free (as in freedom). It’s why open-source advocates go so hard at saying “this is not open-source” when companies just dumps their source code somewhere and dubs themselves open-source for it.
The difference between “open source” and “free software” isn’t a definitional one, but a philosophical one.
