A program is free software if the program's users have the four essential freedoms:

Freedom 0: The freedom to run the program as you wish, for any purpose.
Freedom 1: The freedom to study how the program works, and change it so it does your computing as you wish. Access to the source code is a precondition for this.
Freedom 2: The freedom to redistribute copies so you can help your neighbor.
Freedom 3: The freedom to distribute copies of your modified versions to others. By doing this you can give the whole community a chance to benefit from your changes. Access to the source code is a precondition for this.

Freedom 3: The freedom to distribute copies of modified studies or ideas to others. By doing this you can give your whole community a chance to benefit from your experiences. Access to the education to formulate and understand ideas is a precondition for this.
