I don't think this is a fair critique: they have a pragmatic goal of running a business while being as unrestrictive as possible. With their Apache choice a pragmatic balance was met where developers could use/modify it as they please or use a managed solution from EC or even a managed solution from another company. The ecosystem thrives and their company can thrive. But a managed solution from AWS ends being materially new and different: AWS is able to undercut them on every front, and people end up viewing AWS ElasticSearch as the canonical ElasticSearch. Maybe trademark infringement aside, Amazon didn't break the law but they created an unprecedented situation that changed the effective balance of power which changed whether Apache was achieving their EC's goals or not.
