I used the broader category because in these kinds of situations Free Software brings nothing to the party.
Free Software licensing only places restrictions on what licensees of the software can do with it. The original copyright holder, by virtue of possessing the original copyright, is not subject to those restrictions. That's why dual Free/commercial licensing is such a common choice for companies who are looking to monetize - it's an easy way to maintain commercial control over a product while still getting to call yourself "open".
