“The Free Software Foundation has defined Four Freedoms related
to software. These freedoms apply to users of software, not
necessarily developers. In the view of the FSF, these freedoms are
ethical in nature, so much so that they argue that software which
violates these freedoms is unethical.“Like many other rights, the four freedoms are specific
expressions of abstract freedoms in the context of software. They
represent concrete examples of underlying notions of freedom. You
can see this principle if you ask ‘Why should I be able to run my
own printing press or weblog…?'”
