GNU General Public License

GNU General Public License is a widely used free software license that guarantees end-users the freedom to run, study, share, and modify the software. It was created by Richard Stallman for the GNU Project, a free and open-source operating system developed by the Free Software Foundation. The license is based on the principles of copyleft, which requires that any modifications or derivative works of the original software must also be distributed under the same license, ensuring that the software remains free and open-source. This approach is supported by organizations such as the Electronic Frontier Foundation and the Software Freedom Law Center.
