GPL License

The GNU General Public License (GPL) is one of the most popular free software licenses and has helped drive everything from open-source to distribution. The GPL is a must-know for any developer, business or user that uses the software with respects to which it applies. In this article, we will examine the critical parts of the GPL and discuss its background in software development plus how it applies to users and developers.

What is the GPL License?

GPLThe GPL is a free software license originally written by Richard Stallman for the GNU Project. This prohibits the use of the software in projects that do not promote free and open sourceed ideals, assured it can be used only to enable others with the freedoms they value. The GPL is sometimes called a ‘copyleft’ license because it forces derivative works to also be licensed under the GPL, ensuring that derived versions continue to exist as free software.

GPL License: The Main Features

Freedom : The freedom to use the software for any purpose. The software can be used for any purposes, personal or commercial.

Freedom to Study: The source code of the software is available, and as a user you have access it—knowing how technologies work. Transparency is one of the fundamental principles in open/source.

Change is due to the GPL license from within but not limited The free FOR ALL RIGHTS general purpose with their adaptations. This drive innovation and enable developers to use existing software as base.

The freedom to share: unlimited re-distribution of copies including original and modified versions of the software. But any distributed version also needs to be GPL licensed, so the software should keep being free.

Copyleft: What makes the GPL stand out as a license, of course is its copyleft aspect. That, in turn, means that whatever you make with their GPL-licensed software must also be free and open source under the same license. Software licensed under GPL may not be mixed with proprietary software, instead forcing the code plus any modifications and additions to being always equally open/free too.

Different Versions of the GPL

There are different versions of the GPL and each provides a slightly altered set of terms, conditions or permissions.

GPLv1 (1989): The first one, which created the basis of free software licensing. Simple, but parts of it were unclear until later editions clarified them.

GPLv2 (1991): The second version contained more legal details and the “Liberty or Death” provision, which guards against non-free software being tangled with it.

GPLv3 (2007): The third major version of the GPL was designed to address contemporary licensing issues such as software patents, license proliferation and weren’t general purpose provisions related with DMCA or EUCD-like statutes that can be used against some FOSS.

Lesser GPL (LGPL) : A modified version of the GPL designed to make it easier for libraries. This permits linking with non-GPL software, which offers more flexibility for those developers that want to use GPL libraries in their proprietary code.

The GPL and Its Effect on Software Development

It goes without saying that the GPL has a unique position in software history, and for many years it was at least nominally successful as both licence (though not always by its true spirit)те and arguably more importantly culture. But by perpetuating free and open source software, the GPL helped harbour huge projects like Linux operating system, WordPress or one of a thousand other applications that are cornerstone to how we experience internet today.

Building communities around open-source projects (the single most important aspect of the GPL) Worldwide developers can pool their resources and add to the improvement of GPL-licensed software. Which has resulted in the rapid creation of high quality software that is on par with, and often better than, closed-source alternatives.

Let us break down the implications of GPL for developers and users

When developing your software, licensing it under the GPL means you are making a commitment to open-source values. They have to give back to the community and respect the freedoms covered by GPL. Developers receive contributions to complement and extend their work.

Its primary function is to give users control of the software they use. They are not whipped by restrictive licenses dictating what they can do or change with that software. Especially for organizations not wanting to be tied into proprietary software vendors.
