Neither. Right now AWS seems to be acting in the best interest of the ElasticSearch community, but this doesn't extend to open source as a whole.

For the long-term, the open source community should look to projects where the center of gravity is outside of an open core or FANG company. ElasticSearch went open core a while ago, and Elastic's form of open core is more like MongoDB or Redis than it is like nginx or Docker. As for Amazon, I think I'd rank them below facebook, and I would rank facebook below google and Microsoft, as stewards of open source projects.

My guess is that Elastic is acting the best interest of Elastic and AWS in the best interest of AWS :) I used to like a lot Elastic, we have a rather big cluster work with the OSS version, and I really disliked how they started mixing the proprietary part with the oss one. I hope we will get a good answer from them. Like splitting again the proprietary plugins and/or open sourcing some of the security features :)

AWS, in the short term.

In the long term their actions make it impossible to build any sort of business based directly on FOSS. You have to do support, or hosting, or something else.

Guess what, AWS has a lot more money to do both of those things.

and Amazon will keep right on going sucking up code and giving nothing back.

We need aggressive licensing changes.

Hell, API copyright might be necessary to stop this nonsense. We can still have good licensing in that scenario.
