Not, it's not: https://www.gnu.org/distros/common-distros.html.

FreeBSD, NetBSD, and OpenBSD all include instructions for obtaining nonfree programs in their ports system. In addition, their kernels include nonfree firmware blobs.

It is. We are talking about software licenses, not FSF opinion on software distributions.

Ah, even after all these years I get tripped up on which terms only apply to viral-license open source.

There is just one: “GPL”. I’m not aware of any other viral licenses. But I suspect you’ve meant copyleft instead, which is something different from virality - there are plenty of copyleft licenses, eg MPL, which are not viral.

Maybe that's what I was looking for. FFS, way back in the mists of time I'm pretty sure I had a hat that read "COPYLEFT". You'd think I'd be able to get it correct.
