“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.”
Elastic dropped open source three years ago to fight AWS, and AWS answered with a fork. Now Elastic adds AGPL next to ELv2 and SSPL and calls the whole thing a win. The license changed back only after Amazon had its own fork and Elastic had its AWS partner of the year award. Open source came back once it stopped costing Elastic anything.
