Free software movement

The free software movement refers to those people who advocate the principles of free software (in the freedom sense). Richard Stallman is one of the founders and major exponents of the movement, whose adherents often say they belong to the "Free World".

Members of the free software movement believe the software freedoms listed on free software should apply to all software: they hold that it is immoral to prevent people from excercising these freedoms. Richard Stallman argues that non-free software is immoral because it prevents its users from learning and from helping their fellow man. There is no consensus, however, how these aims should be met. Some believe that software should be freed through legislation; others through boycotts of proprietary software. Still others believe that time will tell, as free software will eventually be technically superior to proprietary software, and will win on the free market.

Supporters of Open Source argue for the pragmatic virtues of free software (aka "open source software") rather than questions of morality. Their basic disagreement with the Free Software Foundation is its blanket condemnation of proprietary software. There are many programmers who enjoy supporting and using free software but make their livings developing proprietary software, and do not consider their actions immoral.

Many members of the Free Software Movement believe that also other materials currently subject to copyright and patent law should be freed. Others acknowledge that there may be some works that should not be freely modifiable, e.g. opinion pieces in order to prevent misrepresentation of the author's beliefs.
