Google's main problem here is they can't tell their side of the story.
If only they had some process where a customer could agree to have Google publicly explain why an account was banned, I think we'd see many more explanations along the lines of "This customer was using Google cloud to launch Ddos attacks" or "This customer sent bomb threats to the president".
How is that a problem? What's stopping them? Google can easily write blog posts or release post mortems or have the dozens of PMs that visit HN talk about it.
Considering these links are all about people with valid businesses and apps, I doubt your examples apply for violations.
Both the law and Googles privacy policy stops them telling the world if you sent bomb threats to the president. That's still your private mail. They can't go looking it it, let alone telling the world about it.

They definitely subject it to all kinds of automated scanning for spam and potentially abuse. The nearest thing to a public statement from Google on the subject seems to be: “very specific cases where you ask us to and give consent, or where we need to for security purposes, such as investigating a bug or abuse”
i.e. there may be abuse cases where they read your mail without asking.
