Come on now, that is a pretty big stretch. And it's not even true, coreutils and glibc implement a lot of SysV and BSD compatibility. My point here is that GNU as an operating system is dead. People can make up some new goals for it but it seems obvious that the original goals have mostly been a failure. Even if you disregard Hurd and count the "FSF approved" Linux distributions, few people actually use those because most of them are just ordinary Linux distributions but with the only major change being that some proprietary packages and drivers are removed. Is that really adding value to the software ecosystem? I personally wouldn't recommend those to anyone beyond hardcore GNU nerds, for most people I'd still say just use Ubuntu.
