IANAL and I am pretty sure they will need to be involved in a serious way to iron all this out. I have my understanding of the intent, which I would not invest money in at this point trying to prove, and that's as much as I can offer. It seems that you can have users search your data in your Elastic+Kibana instance. What they're precluding is you offering an Elastic instance for your customers to load their data into and then search or offer for search to their users.
I understand the intent, but elastic has proven to create legal confusion despite being warned against it and then sue over it in the past when they mixed the APL source and the x-pack source under two different licenses in the same repo and then sued floragunn over copyright violations. They might be technically correct on that lawsuit, but IMHO they knowingly created that situation.
I’d not say “intentionally” as I don’t think that this was the motivation behind the change. I’d consider it “knowingly” - they were or at least should have been aware that the change was going to create confusion about the license that individual code parts and changes were under. It was pointed out at that time.
