Impact that copyleft has on the choice of the software license
Analysis of the impact that copyleft has on the choice of the software license for the project
Definitely, copyleft has a very strong influence on the project, since it is this license that determines how the work will be built. For instance, it is important for developers to know such facts as to whether there are source codes or whether they need to create everything from scratch, whether there are any restrictions or there is complete freedom of ideas and thoughts in the work. And if we have a question about whether the license affects derivative works or not, then we can immediately get an answer that comes out of the lines above and this answer is positive.
Speaking about the variety of copyleft, there are different forms of it, such as strong, weak, and generally no copyleft. In my post, I will look at each of these forms and determine what impact each of them has on the choice of a software license for a project.
The first form I would like to consider is the strong copyleft. This form implies that the software will be created by modifying the original. A strong copyleft creates some restrictions for the developers of this software since in this case the license of the original is preserved. Also, strong copyleft creates some problems when integrating the application. However, this form of copyleft is the best for end-users. One of the important factors of strong copyleft is that the project code will be public, that is, there will be full access to their source code. Linux is just such an example of software with a strong copyleft license. And given the open-source code in Linux, with certain knowledge, a person can change anything in the system, and in the way he wants. So to speak, adjust the system for yourself.
Strong copyleft is the most common form of copyleft, and the strong copyleft General Public License (GPL) is used by most of the world and for good reason. I can say that even though strong copyleft provides some restrictions for developers, having the source code is a huge benefit for the same developers and users at the same time.
The second form of copyleft is called weak and I can say that weak copyleft licenses, as well as strong copyleft licenses, have certain limitations for the developer, but this weak form of copyleft is better at integrating software with non-free systems. The name of this form really corresponds to it, since using a license with this form of copyleft creates more opportunities for the developer.
Weak copyleft, like strong copyleft, has significant benefits for developers, as this form of copyleft is particularly relevant in the case of software libraries that are used to build other programs.
Some of the most common weak copyleft licenses are the Lesser General Public License (LGPL) and the Mozilla Public License (MPL).
Moving on to the last form of copyleft, I can say that it is this form that gives the greatest freedom to developers, the ability to integrate and to create custom applications from this software. Here we can see a really significant advantage for developers. However, a no copyleft license is not the best choice for the end-user.
In terms of popularity, licenses with no copyleft are inferior to strong and weak copyleft, but such licenses exist and their examples can be BSD and Apache licenses.
Overall, after analyzing every form of copyleft, there is a certain advantage to a strong copyleft due to open source. However, if we have to choose a license for a project, we must first of all be based on the requirements of the customer.
