This is really a non sequitur. It's perfectly easy to imagine a large organization which has a disorganized and mismanaged mess for their IT infrastructure, but a great compliance and regulatory culture, or vice versa.
DB happens to have both a broken engineering culture and (at least historically) an even more broken culture of mis-selling and fraud, but there's nothing to say that one always engenders the other.
Note that I am not claiming that Deutsche's IT department is no longer dysfunctional! Just nothing in TFA provides convincing evidence about the current state of affairs.
