The "market confusion" bit has always struck me as disingenuous. The market was never confused about who was offering the old AWS "ElasticSearch Service" or what it was. Elastic's licensing shenanigans and the fork they forced AWS to create have introduced far more long-term confusion. It's certainly not the case that any confusion has been resolved by licensing the ElasticSearch code under three different licenses, all of which are unusual, confusing, and untested in various ways.
