It didn't achieve what Elastic wanted. It didn't lead to more people paying for Elastic licenses, it lead to users switching from Elasticsearch to a fork. And they eventually backpedaled and relicensed again under the AGPL.

Now, it might be better for the Open/elasticsearch ecosystem, because AWS is contributing more, and possibly the competition drives both Opensearch and Elasticsearch to be better. But on the other hand, there is now a split between two incompatible products, and Elastic has certainly lost some trust.
