Based on comments, I think I understand why Purina is not available to everyone, but I don't understand why Optimal isn't still available. My impression is that it wasn't voluntary possibly in response to litigation or perhaps terms of a settlement. Is there any reason why we cannot be informed? For example, is Optimal bound by non-disclosure as required by terms of a settlement?
