«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. It also makes “free software” less visible than “open source,” since it presents “open source” prominently but splits “free software” apart.»
