Copyleft is a software licence that permits individuals to utilise and modify open-source code in their own programs, on the condition that they distribute their modified program to others without charge. Consequently, the code can be utilised and enhanced by anyone without any constraints or limitations.
Copyleft is a form of software licence that permits users to alter or utilise open-source code in their own programs, provided that the resulting software is also open-source and freely accessible to the public. For instance, the GNU General Public License (GPL) is a widely used copyleft licence for numerous open-source software projects. It enables users to modify and distribute the software, but mandates that any changes to the code must also be made available to the public under the same licence. In essence, copyleft licences such as the GPL are intended to foster collaboration and sharing within the open-source community. By allowing users to freely modify and distribute open-source code, copyleft licences help to cultivate a culture of innovation and cooperation, enabling developers to build upon each other’s work to create superior software for all.
