Top-level troll: that's not a "version" of Elastic Search, it's a fork of ES specifically created due to ES's licence change that made it more difficult for AWS to extract money from it at Elastic's expense.

Not that I like either actor in this particular play, but this isn't exactly an example of community oriented goodwill on Amazon's part.

No one's asking for "community oriented goodwill", just "sustainable engineering, correctness, and keeping DuckDB open and MIT-licensed for everyone". OpenSearch is a perfectly good example of Amazon maintaining an openly licensed open-source project.
