The [GNU] Free Software Definition The free software definition presents the criteria for whether a particular software program qualifies as free software. A program is free software if the program's users have the four essential freedoms: * The freedom to run the program as you wish, for any purpose (freedom 0). * The freedom to study how the program works, and change it so it does your computing as you wish (freedom 1). Access to the source code is a precondition for this. * The freedom to redistribute copies so you can help others (freedom 2) * The freedom to distribute copies of your modified versions to others (freedom 3). 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. https://www.gnu.org/philosophy/free-sw.en.html https://www.gnu.org/philosophy/free-sw.en.html
