Free/Commercial is not clear distinction

I assume the free/commercial distinction is meant to differentiate between proprietary, and open source licenses? It's not a good distinction to use, as open source projects can most certainly be commercial, and the term "free" is ambiguous. Many of the software listings use the distinction "proprietary" and "open source", or better, "proprietary" and the specific license, e.g. GPL. See for example https://en.wikipedia.org/wiki/Comparison_of_shopping_cart_software#General_information
