By forking on an earlier instance of the codebase for ES and Kibana they're not only creating an open source version of the code but also attempting a fork of the community - plugin developers, user groups, etc. It's extremely frustrating. EDIT: If folks actively building plugins have felt pain here because of decisions by Elastic, then my view on this point changes considerably, obviously.
I find it very hard to believe there was no compromise to be had here between the current Elastic roadmap for their product and their previous work.
How is this good for users of the current tools? How does this help create better capabilities on a common platform? Will this encourage users to build businesses on elasticsearch open source elements?
I'm not sure where the community ends up after this, so I'm not sure I can support by using AWS' elasticsearch tools.
