Quoting the comment you're replying to:

Those are the key words. With an open source solution someone else can offer a turn-key solution that benefits from economies of scale.

Can Azure offer an OpenSearch service? Probably.

So the idea is you can move from AWS to Azure if you wanted to with open source services underneath.
