In a blog post, CEO Shay Bannon justifies why Elasticsearch no longer appears as free software. Amazon is solely responsible for this step, and its behavior towards the developers of the search engine is unacceptable. Now Elastic has to stand up to the company as the market leader.
Specifically, the ie is that AWS offers Elasticsearch without Amazon cooperating with Elastic. For example, the name Amazon Elasticsearch is a trademark infringement, all attempts to clarify the matter with the company have failed and finally made it necessary to file a lawsuit.
