GNU is one amongst the oldest and best famous open source licenses, if not the known of its kind. It works completely without a personal agreement and makes it easy for developers to publish free software.
gnu gpl WordPress Right under such free software WordPress belongs. WordPress has been released under the GNU GPL license, so any theme or plugin developed for WordPress must have this license due to copyleft. Look here. This means that you can modify, use, and redistribute any WordPress software for free or for a fee.
What is GNU GPL? – Definition
The gnu General Public License was initial revealed in 1989 by Richard Stallmann, co-founder of the gnu Project. In 1991 the second version of GNU GPLv2 was released and in 2007 the latest current version of GNU GPLv3 was released.
The license guarantees the right of free use and modification without the authors being denied the authorship.This is typically done by inserting a duplicate of the official gnu license text attached to the code.
Therefore, each GPL license grants many rights, such as reproducing, distributing, modifying, and making the software publicly available. This why, the publisher must also make the source code available for the public. The best known software, which was under this license, are Linux and WordPress.
For example, you have the following rights when using WordPress:
- Right 1: Everyone is free to use WordPress for whatever purpose they like.
- Right 2: Everyone is free to browse the WordPress source code and customize it to their own needs.
- Right 3: Everyone is free to copy and redistribute WordPress at will.
- Right 4: Everyone is free to improve WordPress and share these community enhancements for everyone to benefit from.
If WordPress were a country, our Bill of Rights would be the GPL as a result of it protects our elementary freedoms.
Matt Mullenweg, co-founder of WordPress
In addition to the rights created by the GNU GPL, the GPL also establishes obligations that licensees must consider if they wish to use their rights.
One of the most important is known as Copyleft.
What is a Copyleft
Copyleft is a GPL clause that guarantees that any software derived from the original must carry the same license as the original version. This means that any derived or modified version of a GPL software, if accessible to the public, must also have the same GPL license. Based on copyright, the Copyleft symbol looks exactly the same, backwards.
