Thanks for the quick response! Let me clarify though.

Each of Elastic, Redis (Labs) and Mongo (and many others) have put licenses in place to explicitly exclude people from taking their code and turn it into a service.

I think that’s fine and their right, as much as making any propriety software (including source available) is someone’s option. But you seem to have a different view about upstream (fully open?) and downstream (scarcity) that I wanted to understand more clearly.
