@lunacb Yeah, basically. Though I am LOLing at the idea of referring to RMS as a "fossbro".
RMS's insistence on usage goes back to at least 2000 with this friggin thing: https://www.gnu.org/gnu/why-gnu-linux.html
Prior to that, it was extremely uncommon to hear anyone utter or write GNU/Linux as far as I recall? Just "Linux".
I also never recall hearing GNU/IRIX uttered even if maybe peeps ran gcc on IRIX?
Debian GNU/kFreeBSD (FreeBSD kernel, GNU userland) exists & I still know no one who uses it.
