Subscriptions are what helps pay the bills so that UNA can continue to be developed. I think if you have a premium license key, then the modules are included. And, if you are a newcomer and choose Cloud hosting by UNA then the modules are included, but, if you are neither, then you download the platform for free and pay for the modules you need/want. Remember, support and development time is taking away people from their own family lives. Let's be fair.
