1. No one says you need to modify/extend something in order to sell a service around it. That's why we have licenses that list exactly what you can do and cannot do with the software.
2. Amazon adds value here by providing hosting solutions for companies using the elastic search software. So it makes sense to call it "Amazon Elasticsearch Service" since that's what it is. I think interpreting this as Amazon built a new competing product but calling it the same name is not the right interpertation. If that's confusing then maybe modifying it to "amazon elasticsearch hosting service" would be the OK thing to do. Not sure if that would make Elastic happy.
3. That's nice of them (really!). Sounds like win-win. But again, it doesn't make anything they do more justifiable.
