Used with preference over the term “open source,” to refer to
the group of practices that relate to sharing software and
distributing ownership of copyright, development, and
management. Typically the word “free” in this formulation refers
to the “freedom” that this approach to technology provides both
users and developers of technology, rather than the cost of the
software licensing/distribution (which is typically “free” as
well by virtue of basic economic pressure.)
