Let's say you are PHP consultant , you set up a Redis + EC2 instances.
You enable a redis enterprise module in that instance.
Well technically speaking you are breaching the license of RedisLabs. You are not allowed to do so without their consent because those modules aren't "bsd" or "mit" they are "Commons Clause".
In short , if you are doing something with the RedisLabs modules ( consulting / hosting / training / support ) you owe $$$ to RedisLabs.
