"Free software" or "free software", first letter capital depending on where in a sentence it is, means either software which is free according to the definition of Free Software Foundation, or it means free as in "no price". The latter however is better described as "freeware", if it does not give any additional freedoms, to avoid confusion (in the same way often the free as in freedom software is called "libre software").
"Free Software" (with both words starting capital), refers to the movement advocating free software with the definition of free as in "freedom" (not necessarily free of price unless it does under "free as in freedom" as well).
A compromise in naming the topic could be "Gratis software list" as this will avoid all ambiguity, because gratis always means "at no price"/"for nothing". Of course we could also just remove all the freeware, or make a new topic without it, and call it "Libre software list" which would avoid ambiguity in the other way, because libre always mean "free as in freedom".
