You don't think the omission of encryption and lack of authentication imply a criminal absence of due diligence.
I guess some huge contracts are in the offing fix those necessary features which should have been built-n in the first instance.
No conspiracy or whatever, just thinking about the complex system which is also vulnerable for some parts.
