Elastic's decision to change its licensing for Elasticsearch and Kibana stems from ongoing disputes with Amazon regarding trademark infringement and the provision of Elasticsearch as a service without collaboration. Despite efforts to resolve these issues through legal avenues and negotiations, Elastic's leadership felt compelled to revise the license to prevent further misuse and confusion within the open-source community. This move was prompted by Amazon's actions, which Elastic claims have misled users and fragmented the community, including the launch of Amazon Elasticsearch Service and the Open Distro for Elasticsearch fork. The licensing change aims to protect Elastic’s intellectual property while maintaining its commitment to open-source values, and it is not expected to impact existing users or customers.
