For the record, the Dilbert comic[0] whence "here's a nickel, kid" mentions Unix, not Linux. macOS is a certified Unix.
Accordingly, Macs c/o Unix have been used to perform real work for decades.
Even so Don Norman, Apple Fellow, wrote the forward to the Unix Hater's Handbook. I say this to say there's serious thought behind Apple's OSes _pre-Unix_ and criticism of Unix. (See e.g. John Siracusa's encomia to the spatial Finder).

So's z/OS, whereas FreeBSD isn't.
Also, there are Linux distros that are certified Unixes: Inspur K-UX, for example.

Ah, yes, the "our favorite proprietary system was killed by Open Systems and we're Big Mad about it" book.
