what aws does is more oss than that what elastic does. elastic also did it because of $$. so neither of them wins.
I can still spin ElasticSearch cluster for my backend and I have somehow open license. Where is open source version of Aurora, Dynamo, DocumentDB, Neptune or Redshift? Where is anything OSS from AWS that is useful outside interfacing with AWS services?
Is it though? Every single one of their blog posts have been focused on spinning their decision as being great for the open source community. What they should have said was - we are a business, have VCs/shareholders and need to make money now, so sorry but the free ride is over.
AWS say they want elasticsearch and kibana to be open source. What they really mean is they want to use elasticsearch without paying their fair share.
