Please don’t use the term “freeware” as a synonym for “free software.” The term “freeware” was used often in the 1980s for programs released only as executables, with source code not available. Today it has no particular agreed-on definition.
Others use the term “FOSS,” which stands for “Free and Open Source Software.” This is meant to mean the same thing as “FLOSS,” but it is less clear, since it fails to explain that “free” refers to freedom.

There is a misunderstanding that the free in free software or FOSS refers to price (and is hence a synonym of freeware). https://www.gnu.org/philosophy/floss-and-foss.html
