This is terrifying. Aren't Backblaze users paying per-GB of storage/transfer? Why should it matter what's being stored, as long as the user is paying the costs? This will absolutely result in permanent data loss for some subset of their users.
I hope Backblaze responds to this with a "we're sorry and we've fixed this."
