Can you build a binary on NetBSD with gcc or whatever, linked to the system libc (or whatever usually happens by default), such that you can copy it over to a FreeBSD or OpenBSD system and it'll just run, without having to install any kind of special compat or emulation layer?
If so, ok, sure, then you have a point. Otherwise, no, those are three distinct OSes, and it's entirely correct to list them as such.
I know you can't mix macOS into that, so the "or 4 if I'm generous" is pretty unfair.

I don't think the author is claiming it means "Operating System", just that "BIOS" is a simple shorthand for "bare metal". Which no, isn't an "operating system" in the classical sense, but it is a standardized set of very low-level system services that sorta vaguely kinda acts like one. And if we consider UEFI rather than old-school PC-BIOS, it's even more like an OS.
Your comment just feels like pedantry for pedantry's sake (and not particularly correct pedantry, at that). Not sure what you're trying to accomplish here by minimizing the achievement.
