@frogzone >(i thought "FOSS" encompassed copyleft but i may stand corrected)
"FOSS" was only intended to be a neutral between free software and "open source", but it even fails to be neutral, as almost all people assume it means gratis, source available software.

If you wish to be neutral, "FLOSS" is the term to use, but why would you want to be neutral between freedom and corporate bootlicking?; https://www.gnu.org/philosophy/floss-and-foss.html
