GPL30only

GPL30only is a licensing scheme used in the context of free and open-source software (FOSS) to specify that a project is licensed under the GNU General Public License version 3 (GPLv3) or later. This scheme is employed to ensure that any derivative works or modifications of the software also adhere to the terms of the GPLv3 or any subsequent version of the GNU General Public License.

The primary goal of GPL30only is to maintain the strong copyleft provisions of the GPL, which require that any distribution of the software or its derivatives must include the source code and allow further modifications under the same license. This approach is designed to protect the freedom of users to study, modify, and distribute the software, while also ensuring that the original license terms are preserved.

Projects that adopt the GPL30only scheme typically do so to align with the principles of the GPL, which emphasize the importance of free software and the rights of users. This licensing strategy is particularly relevant in communities where the preservation of open-source principles is a priority, and where contributors and users expect that their rights will be protected under a robust copyleft license.

The GPL30only designation is often used in conjunction with other open-source licenses, such as the MIT License or the Apache License 2.0, to provide users with a clear understanding of the licensing terms under which the software is distributed. This dual licensing approach can be beneficial for projects that aim to attract a broader audience while still adhering to the principles of free software.

In summary, GPL30only is a licensing scheme that ensures compliance with the GNU General Public License version 3 or later, thereby preserving the copyleft provisions and protecting the rights of users and contributors in the free and open-source software ecosystem.
