Completely off topic but the title made me wonder if there’s any subscription service that cancels you if you don’t use it? Not quite usage based billing - plans that cancel (or pause) without use? I can’t think of any - terrible business model of course

In the spirit of yes, and: how about a subscription similar to a pay as you go phone plan? Pay for the month, and when you don't pay, then you don't get to keep going. After a couple of months, they unsubscribe you, get rid of your account, etc. More often than not, the first thing I do when I sign up for a service is cancel it (after confirming I can use it for the billing period).

There is a coffee shop here that has a membership plan (you can roast at the shop it’s cool. Membership = no charge to roast and discounts on beans). It’s monthly and you have to re-up to keep it. It’s great and I’m happy to support them.
