Mozilla Public License
Noun · Open Source
Definitions
A weak copyleft license, commonly abbreviated MPL, that requires modified files to remain under the MPL while allowing larger combined works to include code under other licenses. It is often chosen when projects want some reciprocity without full GPL-style reach.
In plain English: An open source license that requires changes to licensed files to stay open while allowing broader mixed-code projects.
Example: "The Mozilla Public License worked for them because they wanted file-level openness without forcing every adjacent module under the same terms."
