Elastic did not explain its strategic shift at the time. But industry observers interpreted the changes as a response to increasing competition from AWS, which had incorporated Elasticsearch’s code and search functionality into its own suite of computing services.

Elastic isn’t the only open source cloud tool company currently looking over its shoulder at AWS. In 2018 alone, at least eight firms have made similar “rule changes” designed to ward off what they see as unfair competition from a company intent on cannibalizing their services.

In his blog post, Cockcroft argued that by making part of its product suite proprietary, Elastic was betraying the core principles of the open source community. “Customers must be able to trust that open source projects stay open,” Cockcroft wrote. “When important open source projects that AWS and our customers depend on begin restricting access, changing licensing terms, or…
