[D.N.A] Elasticsearch and Kibana can be called Open Source again. It is hard to express how happy this statement makes me. Literally jumping up and down with excitement here. All of us at Elastic are. Open source is in my DNA. It is in Elastic DNA. Being able to call Elasticsearch Open Source again is pure joy.
[LOVE.] The tl;dr is that we will be adding AGPL as another license option next to ELv2 and SSPL in the coming weeks. We never stopped believing and behaving like an open source community after we changed the license. But being able to use the term Open Source, by using AGPL, an OSI approved license, removes any questions, or fud, people might have.
[Not Like Us] We never stopped believing in Open Source at Elastic. I never stopped believing in Open Source. I’m going on 25 years and counting as a true believer. So why the change 3 years ago? We had issues with AWS and the market confusion their offering was causing. So after trying all the other options we could think of, we changed the license, knowing it would result in a fork of Elasticsearch with a different name and a different trajectory. It’s a long story.
What a deceptive, and contradictory statement to make, kek. The SSPL is AGPLv3 with Section 13 modified. The net-difference is just one section between personal and commercial use.
The SSPL is based on the GNU Affero General Public License (AGPL), with a modified Section 13 that requires that those making SSPL-licensed software available to third-parties (modified or not) as part of a “service” must release the source code for the entirety of the service, including without limitation all “management software, user interfaces, application program interfaces, automation software, monitoring software, backup software, storage software and hosting software, all such that a user could run an instance of the service using the Service Source Code you make available”, under the SSPL. The chapter structure of the Server Side Public License is identical to that to the AGPL, except that the GPL preamble and application instructions are stripped from the license text.
And meanwhile, have a look at the Elastic License 2.0:
The Elastic License 2.0 applies to our distribution and the source code of all of the free and paid features of Elasticsearch and Kibana. Our goal with ELv2 is to be as permissive as possible, while protecting against abuse. The license allows the free right to use, modify, create derivative works, and redistribute, with three simple limitations:
You may not provide the products to others as a managed service
You may not circumvent the license key functionality or remove/obscure features protected by license keys
You may not remove or obscure any licensing, copyright, or other notices
We tried to minimize the limitations just to those that protect our products and brand from abuse.
You can keep lying to yourself, Shay Banon.
I don’t follow. ElasticSearch was only available under proprietary source-available licenses. Now, it’s also available under the AGPL, which is open source, meaning ElasticSearch is now open source software. What part of this is deceptive or contradictory?
Because it does not comply with the Open Source definition?
SSPL violates these two:
- No Discrimination Against Fields of Endeavor
The license must not restrict anyone from making use of the program in a specific field of endeavor. For example, it may not restrict the program from being used in a business, or from being used for genetic research.
- License Must Not Restrict Other Software
The license must not place restrictions on other software that is distributed along with the licensed software. For example, the license must not insist that all other programs distributed on the same medium must be open source software.
ELv2 violates these four:
- Free Redistribution
The license shall not restrict any party from selling or giving away the software as a component of an aggregate software distribution containing programs from several different sources. The license shall not require a royalty or other fee for such sale.
- Derived Works
The license must allow modifications and derived works, and must allow them to be distributed under the same terms as the license of the original software.
- Integrity of The Author’s Source Code
The license may restrict source-code from being distributed in modified form only if the license allows the distribution of “patch files” with the source code for the purpose of modifying the program at build time. The license must explicitly permit distribution of software built from modified source code. The license may require derived works to carry a different name or version number from the original software.
- No Discrimination Against Fields of Endeavor
The license must not restrict anyone from making use of the program in a specific field of endeavor. For example, it may not restrict the program from being used in a business, or from being used for genetic research.
Simply putting in the AGPLv3 does not remove unfair restrictions. I mean, SSPLv1 is not compatible with AGPLv3.
Do you… not know how multi-licensing works? You can use the project’s code under the terms of whichever license you prefer, you don’t use all three at once. Simply putting the AGPLv3 does remove unfair restrictions, because it means you don’t have to use either of the proprietary licenses the project was previously only available under.
And which parts does the AGPL violate? Because that’s what the article is about: it becoming available under the AGPL.
I think you are confused. You can use ELK under AGPL with this news going forward. The fact that they have to retain SSPL, too, because of previous contributors under that license, has nothing to do with the fact that you can use AGPL going forward. I’ve read your other responses,but they all seem to go down the same seemingly incorrect direction.
Am I missing something?
