So... I am company A that provides a service to you, for free. The service I provide is useful to you. I will always keep the stuff you upload to my service. Since lots of people also like the service that I provide, and because the nature of my service is expensive to maintain for all of the people who use it, I need to make some revenue from my service in order to maintain it. I will always keep your stuff for you, and if you use it a little bit its completely free. But if you really, really like to use my service, I just ask that you pay me a little bit of money since you are getting value out of it. In the event that you forget to pay me, I will still keep your stuff but you'll only have limited access to the service. When, or if, you want to use the service full time again, just continue paying me a little bit of money. So, does this basically some it up?
