A fundamental part of healthy business relationships is value for value. E.g., you give me money, I give you a sandwich, you take the sandwich, eat it, and are happy with it. If you keep paying me for sandwiches but I don't give them to you, that's not healthy. Ditto if I put them on the counter but you stop taking them.
Personally, I think there should be a law that all service/software subscriptions auto-suspend after 30 days of non-use. Because right now there's a big incentive for businesses to get you to sign up for things they think you're not going to use, and to keep on charging you even though they know you're not using it.
