Top 5 GPL License Questions Answered

1. What is copyleft?

Copyright is a law that restricts the right to use, modify, and share creative works without the permission of the owner. When an author releases a program under a copyleft license, he makes a claim on the copyright of the work and issues a statement that other people have the right to use, modify, and share the work as long as the reciprocity obligation is maintained.

This means that any software that is written based on any GPL  must be released as open-source. If any software that uses any GPL open source component. that means it has to required release its full source code and all of the rights to modify and distribute the entire code.

2. Can you sell GPL Products?

Yes, the GPL license allows selling the original as well as the modified products. However, free software is referred to as free in terms of freedom to use not in terms of price. As Richard Stallman explained, free software means free as in “free speech,” not free as in “free beer.”

3. Is GPL safe?

Yes. GPL doesn’t have anything to do with the Source code. It’s just a license that governs its usage and distribution.

4. Does the GPL license require the author to release the modified source code?

Under the GPL License, it requires you to release the modified source code only if you release the modified program. If you have modified a program’s code for personal use, then there is no need to release it.

5. What is the difference between GPLv2 & GPLv3?

It is always been some confusion regarding the difference between GPLv2 & GPLv3. The FSF tried to add more clarity to GPLv3 as to when the reciprocity obligation is triggered. The FSF even wrote a new GPL license, the Affero license, to the “ASP loophole”.

In addition, the FSF decided to improve the compatibility of the GPLv3 with other licenses. To combine two codes into a larger work, both the applications must permit it. If those rights are imparted by both the programs’ licenses, they are compatible. By making the GPLv3 more compatible, the FSF increased development options.

The third difference between the two versions is that the GPLv3 was written in an effort to increase usage globally. The language used in GPLv3 to describe the license rights were modified to ensure that international laws will interpret it as the FSF intended, unlike the language used in GPLv2, which is considered very US-centric. GPLv3 also permits developers to add local disclaimers, which also helps to grow its usage outside the US.
