It's interesting you mention this - Even Elastic started with this same model but then had some conflicts with Amazon being able to monetise ElasticSearch much more than Elastic themselves - so they eventually changed license and then Amazon forked into OpenSearch.. Here's the link for more context - https://www.elastic.co/blog/why-license-change-aws

Btw, wishing you best with your project!
