| | Introduction to Free Software, Free Society - GNU Project - Free Software Foundation (FSF) |
 | | "Free" has different senses, only one of which refers to "price." A much more fundamental sense of "free" is the "free," Stallman says, in the term "free speech," or perhaps better in the term "free labor." Not free as in costless, but free as in limited in its control by others. |
 | | Free software is control that is transparent, and open to change, just as free laws, or the laws of a "free society," are free when they make their control knowable, and open to change. |
 | | Using the power of copyright law, "free software" not only assures that it remains open, and subject to change, but that other software that takes and uses "free software" (and that technically counts as a "derivative work") must also itself be free. |
