Not OP and not really invested. You can probably replace "exploiter" with provider. A user uses the software directly, a provider provides it to users. Amazon can be both simultaneously, they can run ES to analyze sales and find out what products of third party sellers are worth copying, and they can also offer ES as a service to other users. That kind of difference is pretty common in non-source-related things, e.g. you can use the API for your business, but you can't resell access to the API.
