In summary, the conversation discusses the comparison of free and open-source software licenses, including the three main classes of open-source licenses: GPL-like, LGPL-like, and BSD-like. The main features compared are the ability to link with code using a different license and the ability to release changes under a different license. The GNU General Public License (GPL) and Lesser GPL are also mentioned, along with their intended purposes. The conversation concludes with the recommendation of using the MIT license to avoid complicating matters.

Comparison of free and open-source software licenses - Wikipedia
Open Source Licenses | Open Source Initiative

There are oodles of open-source licenses that various people and organizations have composed, and I find it rather bewildering. In fact, someone composed an article on license proliferation for Wikipedia.

The main features compared in Wikipedia's comparison are
  1. Link with code using a different license
  2. Release changes under a different license

There are thus three main classes of open-source licenses:
  • GPL-like: (1) no, (2) no
  • LGPL-like: (1) yes, (2) no
  • BSD-like: (1) yes, (2) yes
There are none with (1) no, (2) yes.

The GNU General Public License (GPL) is intended to simulate absence of copyright in the present of copyright. GPLed code also "contaminates" whatever code it is included in, a rather controversial feature.

The Lesser GPL is intended to permit linking of code released on GPL-like terms with code under other licenses, like proprietary code.

BSD-like licenses permit releasing modifications under different licenses, like making them proprietary. The original still remains open.

Even with this classification, there's still a rather sizable field of possibilities in the LGPL-like and BSD-like categories. Any comments or recommendations?

I don't want to make things any more complicated than they need to be so I use the MIT license.
 

1. What is an open-source license?

An open-source license is a legal document that allows others to use, modify, and distribute software that has been made publicly available by the creator. It ensures that the software remains free and open for anyone to use and contribute to.

2. Why is it important to choose a favorite open-source license?

Choosing a favorite open-source license is important because it determines how others can use and distribute your software. It also ensures that your work remains free and open for the community to benefit from and improve upon.

3. What are the different types of open-source licenses?

There are various types of open-source licenses, including permissive licenses (such as MIT and BSD), copyleft licenses (such as GPL), and dual-licensed licenses. Each type has its own terms and restrictions, so it's important to research and choose the one that best fits your needs.

4. Can I change my favorite open-source license?

Yes, you can change your favorite open-source license, but it's not recommended. Once a software has been released under a certain license, it cannot be changed. However, you can release future versions of the software under a different license.

5. Are there any limitations to open-source licenses?

Yes, there are some limitations to open-source licenses. For example, some may require that any modifications to the software be released under the same license, while others may require that any commercial use of the software be approved by the original creator. It's important to carefully read and understand the terms of your chosen open-source license.
