I think you've highlighted an inaccuracy, or at least a lack of clarity, in the Wikipedia article. I guess a Wikipedian could argue it should be interpreted as "for any purpose depending on the chosen licence", but that's definitely not clear.

Re: Open source vs Free software, this is a matter for debate (the tendency being too associate Free software with the more copyleft/viral/gnu-ish side of things), but I would definitely say that both involve explicit licencing, as opposed to potentially implicit " all rights reserved " style regional copyright.

I would usually use the term "FLOSS", for Free-Liberte, OSS"

The L part clarified the type of freedom, as the FL clarifies that it's not just OSS.
