@jon.strabala and @ingenthr @steve I really appreciate you answered this and all my past unanswered questions.
I really believe that if you could allocate more resources to this community (starting with all the unanswered questions on this forum), Couchbase will become by far the most loved NoSQL DB
The technology is amazing and mature enough, now, it is time to have amazing documentation and support, and I promise the sales will come as most of your clients just need to have support and licenses just to pass their internal audits. The companies/individuals who are using your support without paying at this time will become your advocates on their current jobs and next ones, so in the end, as long as your technology is loved and used in every company, sales will come.
Also, these users which are consuming now support resources without paying for licenses will help you find bugs, or create enough questions/answers that in the end, the support cost will be lower for your company as the entire community will use this documentation without putting pressure on your support team.
The terms and conditions should just stipulate (probably they already stipulate this) that you are not allowed to use the technology in a production environment without a valid license.
