The whole concept of claiming that GNU is the actual OS never made much sense to me. Like yeah, glibc and coreutils are very major components, but so is the init system, and the package manager, and the WM, and the DE… I don’t really understand why RMS draws the line at GNU arbitrarily other than to stroke his own ego. Following his underlying logic, shouldn’t I call my system Plasma/KWin/pacman/systemd/GNU/Linux?
None of this is directed at you btw, it’s just something that always springs to mind for me whenever this topic comes up.
