A few reasons: - you have legal obligations no matter what the customer wants, eg, Amazon and storing transactions for tax reasons - you do actively delete most of their data, eg profiles, but “deleted=true” on their central account record is needed to propagate the deletion to other systems, eg, customer analytics - you tombstone it for efficiency reasons and only periodically delete the records as part of your checkpoint/backup procedure; similarly CDN deployments - you delete all the live copies, but tell customers “retained up to 90 days” because you need backups to age out I’m not saying companies are all innocent — but there are some legitimate reasons that deletions aren’t fully instant.
