I think it's nuanced. I'm currently managing an engineering team on an interim basis. During standup I noticed that most engineers were talking about 'elastic' or 'elasticsearch' but one was talking about opensearch. I asked them to clarify that for me and they told me that they transitioned to AWS opensearch but still use the old name for the product often - that might point to the strength of the Elastic brand.
