A policy is just their way of doing things, written down.
It’s not magic.

To reiterate, "policy" is just explicitly specifying "that's just the way we do things around here"
There are plenty of policies that state that they may be changed by one side or that exceptions may be made in cases where the wording doesn’t cover the intent.
The Apple store policy for example says this.
In this particular case, the ambiguity is exactly that - Google didn't say what what real policy was broken or how.
Given the information in the article, you can't verify any of the traffic or actions that were supposed to break policy. After all Google wrote, "We understand that you may want to know more about the issues that we’ve detected. Because this information could be used to circumvent our proprietary detection system, we’re unable to provide our publishers with information about specific account activity."
"We understand that you may want to know more about the crimes that we’ve detected. Because this information could be used to circumvent our proprietary policing system, we’re unable to provide defendants with information about alleged criminal activity."
You’d think there would be examples of people doing this, but so far I haven’t heard of them.
No lying, no ambiguity. They can't reinstate this account.
Should they change their policy so that after that change, they can? Maybe, but good luck getting them to.
