I think it’s significant in this case that most of the development of ES and the underlying engine is done by Elastic. This re-licensing is only of interest because it means most ongoing work on the project will now happen under the new license. If that was not the case nobody would care, the contributors could fork back to Apache 2.0 and continue. After all, the ElasticSearch license used up until 7.1 also allows me to fork the project under a new restrictive license, but nobody is likely to care if I did.
