Elastic Java clients are no longer open source

This is getting more scarier as days passes by: it seems Elastic is burning bridges all around their own territories effectively locking-in users to their ecosystem.
This has, unfortunately, some conseguences on the opensearch side: what should opensearch do about all the connectors and bindings for the different programming languages currently available ? A lot of them are already integrating anti-competitive measures as it has been reported and I guess we should expect all of them to do the same very soon.
