MPLcontaining

MPLcontaining is a term used in the context of software licensing to describe a practice where a software project includes code from another project under a different license, often with the intention of making the original project's license more permissive. This can be done by including code snippets or entire files from a project licensed under a more restrictive license, such as the GNU General Public License (GPL), into a project licensed under a more permissive license, such as the MIT License.

The primary goal of MPLcontaining is to create a "hybrid" project that combines the permissive nature of the MIT License with the copyleft provisions of the GPL. This can be seen as a way to leverage the strengths of both licenses, allowing developers to use the code freely while still enforcing certain conditions on derivative works.

However, MPLcontaining is a controversial practice. Critics argue that it can lead to confusion and ambiguity in licensing, making it difficult for developers to understand the terms under which they can use and distribute the code. Additionally, it can be seen as a form of license proliferation, where multiple licenses are used within a single project, complicating the licensing landscape.

Despite these concerns, MPLcontaining remains a topic of discussion in the open-source community. Some developers and projects have embraced this practice, while others have chosen to avoid it. The debate continues, with proponents arguing that it can facilitate innovation and collaboration, and critics warning of potential legal and practical issues.
