@charlie_root That's some very interesting thinking.

That's like to trying to say: "This well isn't poisoned, it's composed on 99.5% water and 0.5% poison, as it's mostly water, it's not poison - even though the well water is poisoned and thus undrinkable".

I reckon Linux is 0.2-0.5% proprietary malware, which makes the whole thing proprietary malware, unless you manage to remove those parts.

Yes, Arch ships GNU coreutils, but that's only one collection of GNU software and Arch also ships other GNU software.

@adiz There's no need to repeat yourself, Linux has only ever been a kernel.

Here's some proprietary software that can be found in Linux (there's plenty more):
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/drivers/net/appletalk/cops_ffdrv.h
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/drivers/net/appletalk/cops_ltdrv.h
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/arch/powerpc/platforms/8xx/micropatch.c (license identifier is a lie and although the arrays are called "data", that's executable software)

GNU Linux-libre is a project that patches out proprietary software from Linux, which respects your freedom and also happens to be one of the few versions of Linux that can be distributed without infringing the GPLv2 (the GPLv2 automatically terminates on infringement, so by distributing a version of Linux that's proprietary software, you have lost legal permission to distribute Linux (some people claim that the proprietary software contained within counts as mere aggregation, but it doesn't look like aggregation to me, as the drivers and the proprietary part are often updated in lockstep)).
