Why is there a charge for deleting data? If I want to stop using the service or just lower the storage charge, I need to pay for that? Scrubbing I can understand if scrubbing is not mandatory, but deleting should just be marking data as free to overwrite so someone else can be charged.

I'm not speaking on behalf of C14 or similar service, but the charge for deleting data isn't very new. Quoting from http://aws.amazon.com/s3/pricing/

  For objects that are archived to Glacier, there is a pro-rated charge of $0.021 per gigabyte for objects deleted prior to 90 days.

  Objects that are in Standard – Infrequent Access have a minimum 30 days of storage, and objects that are deleted, overwritten, or transitioned to a different storage class before 30 days incur a pro-rated charge equal to the storage charge for the remaining days.

The difference that I see here is that C14 appears to charge for deletion regardless of the access.

Maybe it's a way on ensuring income for a certain duration on capacity freed up by way of such deletes.
