A generic term for Open Source and Free Software is:
SLOFF OS/FS FLOSS GPL Libre Software
FLOSS
Rather than dwell over the finer points of Open Source and Free Software, the community has started referring to them collectively as Free and Open Source Software (FOSS). The English word “free” can mean “free as in lunch” (as in no cost) or “free as in speech” (as in no restrictions). This ambiguity led to the inclusion of the word “libre” to refer to the latter definition. Thus, we end up with Free/Libre/Open Source Software (FLOSS).
