IMO this is very stupid: don't let past dictate future. UNIX is history. History is for historians, it should not be the basis that shapes the environment for engineers living in present.
The point is that we always exist at a point on a continuum, not at some fixed time when the current standard is set in stone. I remember setting up Solaris machines in the early 2000s with the painful SysV tools that they came with and the first thing you would do is download a package of GNU coreutils. Now those utils are "standard", unless of course you're using a Mac. And newer tools are appearing (again, finally) and the folk saying to just stick with the GNU tools because they're everywhere ignore all of the effort that went into making that (mostly) the case. So yes, let's not let the history of the GNU tools dictate how we live in the present.
Well, even “Unix” had some differences (BSD switches vs SysV switches). Theoretically, POSIX was supposed to smooth that out, but it never went away. Today, people are more likely to be operating in a GNU Linux environment than anything else (that just a market share fact, not a moral judgement, BSD lovers). Thus, for most people, GNU is the baseline.
