Actions speak louder than words. Amazon's words [1] were backed up by action- specifically, the public release of Open Distro for Elasticsearch and several useful, advanced features under an Apache 2.0 license.

This post from Elastic consists of vague claims of 'FUD' and of their commercial code being 'bluntly copied', without any further clarifying details or responsive action to back them up. (E.g., if you have real evidence of Amazon copying proprietary code, which I doubt, then announce the copyright infringement lawsuit you have just filed, don't weakly allude to your grievances in a blog post.)

Conspicuously, the post did not contain any defense or even mention of Amazon's key accusations of "significant intermingling of proprietary code into the code base", or its claim that "the innovation focus has shifted from furthering the open source distribution to making the proprietary distribution popular." The only response offered is a vague, generic "we believe in open source" - again with no concrete action backing up those empty words.

If this is the best and only response Elastic is able to offer, I fully expect Amazon to keep the high ground in this controversy.
