> You basically never want storage to be automatically deleted even if your program suddenly uses a surprising amount

In most use cases you're right. But never? Not true, not all storage is used the same way. And the thing is, why should Amazon decide which use case is valid or not? I might care more about being able to afford the service than to keep the data around, depending on what kind of service I offer my user. As a platform provider, they should be agnostic, but their greed for money is shining through their willingness to be a true platform provider.

There are rules in S3 to move files or delete them after a period of time.

And perhaps most useful rule is to move them to cheaper tiers of storage. For example, Glacier Deep Archive is super cheap for storage since it's $0.99 per terabyte-month.
