The Lambda License
Copyright (c) 2024 Sylv <[email protected]>
The Lambda License is an open license meant to better protect the rights of software authors. It does not adhere to the usual definition of "Free Open Source Software" (FOSS), but rather we aim to strike a middle ground between the freedom of consumers and the protection of the authors' work.
We believe traditional FOSS licenses allow companies or other individuals to exploit software authors freely by having their work shared in a way they don't agree with or that is detrimental to their business. This license aims to give control of artifacts back to the authors and support an open code community, while still allowing source code to be easily modified and shared.
In short, you may share or modify the source code as you wish, as long as the work stays under this license, and if you have modified the code, you must: (a) State your changes if you don't use an SVC like Git (b) List the original authors (as listed in the copyright at the top of this license)
When sharing binaries, you must adhere to a few more rules. In particular, you will need written approval from the original authors. If they don't answer you after 60 days, they are considered to be implicitly agreeing. Please note that you have to request in good faith, spam won't be accepted. You will also need to make the source code available and document where to find it.
If you are running a modified version of this software on your servers and users can freely interact with it, you will need to make your source code public the same way.
The precise terms and conditions can be found below:
1.1. "Source Code": The Source Code is any digital files or tools that are part of the work covered by this text and/or used in the creation of Binaries, preferred for making modifications. This does not include any publicly available tools or libraries. This may include textual or binary digital files.
1.2. "Binaries": Binaries correspond to any form of the work other than the Source Code.
1.3. "This License": This License corresponds to the full text of this document.
1.4. "Copyright Notice": The Copyright Notice corresponds to the second line of This License, starting with "Copyright (c)".
1.5. "Project Owner": The Project Owners are all physical persons or legal entities mentioned in the Copyright Notice. They may be referred to by an alias.
1.6. "You": "You" corresponds to an individual or a legal entity exercising rights under this License. For legal entities, "You" includes any entity that controls, is controlled by, or is under common control with You. For purposes of this definition, "control" means (a) the power, direct or indirect, to cause the direction or management of such an entity, whether by contract or otherwise, or (b) ownership of more than fifty percent (50%) of the outstanding shares or beneficial ownership of such an entity.
You may copy, modify, merge, publish, distribute, and/or sell copies of the Source Code under the following conditions:
2.1. The Source Code and any derivative work of the Source Code are licensed under This License.
2.2. You must explicitly state your changes, if any, in a prominent place. 2.2.1. Commit history as provided by source version control software programs is considered to fulfill 2.2.
2.3. If you modify the Source Code in any way, You must list the original Project Owners in a prominent place. 2.3.1. Commit history as provided by source version control software programs is NOT considered to fulfill 2.3.
2.4. You may add your name to the Copyright Notice, but You must not remove any name from the existing Copyright Notice.
You may share, publish, distribute, make derivative work, and/or sell copies of Binaries, or license the right to do so, under the following conditions:
3.1. The Binaries and any derivative work of the Binaries are licensed under This License.
3.2. You must make the Source Code used to create the Binaries publicly available, free of charge. 3.2.1. You must clearly document in the Binaries, and respond to requests asking how to obtain the aforementioned Source Code.
3.3. You must obtain written approval from all Project Owners to use their work as mentioned above. 3.3.1. This authorization is free of charge, royalty-free, global, non-exclusive, revocable and non-transferable. 3.3.1.1. Revocation can be pronounced at any time (known as the "Revocation Date") by any Project Owner, upon written notification to You. 3.3.1.2. If and when revocation is pronounced, You cannot make use of any rights under Section 3 for any and all work made after the Revocation Date. The revocation does not retroactively apply. 3.3.2. The Project Owner may impose any additional clause on their authorization within the limits provided in 3.3.1. 3.3.2. If a Project Owner fails to reply within 60 calendar days upon receiving a good-faith written request sent through their primary email, an irrevocable authorization from that Project Owner is implicitly granted. 3.3.2.1. A written request made within 180 calendar days upon receiving a negative answer is considered implicitly rejected and does not qualify for 3.3.2.
If you offer users the ability to interact remotely through a computer network with a Binary created from a modification of the Source Code, you must make the modified Source Code publicly available, free of charge. You must also clearly document and respond to requests asking how to obtain the aforementioned Source Code.
