👉 GNU General Public License (GPL) engineering refers to the principles and practices that ensure software developed under the GPL remains free and open for all users, developers, and communities. It mandates that any derivative work or modified version of the software must also be released under the same GPL license, ensuring that the freedoms to use, study, share, and improve the software are preserved. This licensing model fosters a collaborative environment where developers can build upon existing code without restrictions, promoting transparency, security, and innovation. GPL engineering emphasizes community-driven development, where contributions are openly shared, and the software's integrity and accessibility are maintained throughout its lifecycle.
