Shay Banon writing on the Elastic blog:
[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.
[Like That] The good news is that while it was painful, it worked. 3 years later, Amazon is fully invested in their fork, the market confusion has been (mostly) resolved, and our partnership with AWS is stronger than ever. We were even named AWS partner of the year. I had always hoped that enough time would pass that we could feel safe to get back to being an Open Source project – and it finally has.
Cloud companies were making open source licensing for infrastructure software pretty non-viable. Here’s a story with a slightly happy ending.
