Am I the only one having a very, very hard time parsing much on threat modeling out of this article?

Wikipedia seems to confirm my understanding as to what threat modeling is: "Threat modeling is a process by which potential threats, such as structural vulnerabilities or the absence of appropriate safeguards, can be identified, enumerated, and mitigations can be prioritized."

There's a little bit in the article about mapping your system, and maybe at looking at interfaces and interaction points? Don't see anything about attack vectors, modes of detection and response, etc.

Also, why only the look at digital security? Being aware of how your systems interact with the physical environment can have a strong influence in how you approach architecture, even if the answer boils down to "our infrastructure team handles that".
