GPLv2

GPLv2 (GNU General Public License version 2) is a free software license that allows anyone to use, modify, and share software freely. However, it requires that any derived versions or redistributed copies must also be made available under the same license. This ensures the software and its improvements remain open for everyone. GPLv2 emphasizes the importance of transparency and collaboration, promoting a community where software remains free and open, preventing proprietary restrictions from being placed on modified versions. It’s widely used in open-source projects to protect users' freedoms to study, change, and distribute software.
