So in floss, that would be free free open source software.
Which doesn't seem right? Unless there is another meaning to libre I'm missing?
Interesting!
edit: could mean Gratis and/or Libre Open Source Software
I do like the idea of distinction between GLOSS and PLOSS, but we've got enough acronym soup at this point that I'd say just stick with FLOSS.
Also, many people who only speak English don't know the word Libre.
Because then people would think they are losing something by using it? /s
It is in opposition to "restricted" software where you are restricted in all of those. (Copyleft software restrict others from adding more restrictions, which is defensible but some BSD proponents disagree)
Libre is, as many have said, just the Latin word for Free. You'd still have to explain what it means in this context.
"Open Source" has similar problems: many think that it's enough for source code to be available for inspection for software to be called "Open Source", but it is just a another attempt to market a philosophy under a particular name.
These constructs are created to have a special meaning to promote an ideology, and are thus usually capitalized in English. This is nothing uncommon, and attempting to use these—now accepted—phrases to mean something else is bound to cause confusion. So, just like you learn what a "programming language" or "HyperText Transport Protocol" is (yes, one transfers a lot more than just "HyperText" over it), if you are in IT, one should learn what "Free Software" and "Open Source" mean.
But if you paid for it, they ain't allowed to, of course.

Update: The distinction is important. It also entails that people should be able to earn a living by providing FLOSS software. Many people that don't know much about FLOSS think of it as the "Free beer" variant (something promoted by much of big tech, which is seemingly free). There can be good business models attached to FLOSS (though devs have a very hard time to monetize in practice).
I heartily applaud anyone trying to monetize FLOSS based on decent principles and values, rather than just bottom-line, willingly taking the hard road of founding a bootstrapped, sustainable business.
This is also what the phrase "free as in speech, not as in beer" attempts to disambiguate.
(Notably Microsoft had the gals to do it in its English PR and translate all over the world, including literal translations to Latin languages where both words are completely different.)
