Free software is simply software that respects our freedom -- our freedom to learn and understand the software we are using.

"Copyleft is a general method for making a program or other work free, and requiring all modified and extended versions of the program to be free as well. The simplest way to make a program free software is to put it in the public domain, uncopyrighted. This allows people to share the program and their improvements, if they are so minded.

When explaining why Free Software is important, one question that often comes up is: “do I really need the software freedom?”

The free software community understands that free software gives the user more freedom than proprietary software. Proprietary software confines its users, prohibits them from making changes that would allow everyone to benefit, etc. Free software advocates (myself included) have a habit of claiming that using free (libre) software means the same thing as having freedom.

Free software is software you can study, modify and share without restriction. But unlike proprietary software, there is no big budget marketing campaign behind it. Rather, people discover it and come to value the freedom it provides. What are these people's motivations for working on free software? Why is community and sharing so important? Why should everyone be using free software?

"Hello, finally. This is an unusual talk in which I'm going to start by explaining the ideas of free software, and then go on to talk about how they extend to some things other than software.

"...Free software is software that gives you the user the freedom to share, study and modify it. We call this free software because the user is free. To use free software is to make a political and ethical choice asserting the right to learn, and share what we learn with others. Free software has become the foundation of a learning society where we share our knowledge in a way that others can build upon and enjoy..."

Imagine you, as a happy user of standard, proprietary software, were told that you should use 'free' software, so that you would have the freedom to use and share your software however you wanted. This argument would not convince many people on its own.

RMS (Zagreb on March 9th 2006): "... Many people suggest a two stage solution. They say, first, let's teach people to use Free Software, and then, once they're using it, we'll teach people to appreciate the freedom.
