Earlier quoted context omitted.
Not really, someone could just use that misleadingly too, just as with "open source". "Open Source" already doesn't cover these special licenses, instead, the "source available" is used. Any also acknowledges this actually - the license they are using is called the "Any Source Available License 1.0".
After a bit of brushing up on my acronyms, one could indeed use FOSS or FLOSS to denote that a piece of software is either free (or libre) or just open source [0]. The term "open source" is not referring to software with a free license, but to software whose source code is available to the public irrespective of license [1].
