That’s just like people who are going to be “smart” and use a card with a low credit limit to attach to their hobby AWS accounts.

Just because the charge was declined when you were billed doesn’t mean you don’t owe the money.

A subscription is a bit different as you pay in advance. If the charge fails, you generally lose access to the subscribed service. That's not the same as using an AWS resource, being invoiced for that use, then not paying it.

That’s fair and in most cases, you can just update your card information and nothing is lost. But what if it is for a renewal of something like a domain name or backup service where you would lose data if you don’t renew?
