Do you have a good understanding of the legal differences? My understanding is there now an open source license that anyone can fork, including companies basically committing IP theft, and then a basic license that is free unless you are selling Elastic as a service? The idea is that Elastic would put all improvements into Elastic Basic, and Amazon can't use this source code in its forked version?

IMO, it doesn't seem like a near-term risk, but could Elastic ever change its basic license so it costs money for everyone?
