She was probably repeating behaviors she learned in academia. These kinds of extremely toxic "don't just apologize for disagreeing with me but also give me the name of every person involved for collective punishment" is a classic move for academic tyrants throwing weight around. The understanding there is that they will then move to cut off every named person from power or access to academic resources. Google did the right thing by protecting their people.

I have watched it happen multiple times that someone from academia joins a research group at a large corporation and finds out to their chagrin that they can't just overtly bully colleagues as easily without tenure.

edit: And it looks like Mitchell immediately left an angry comment about being called a "linguist" despite the article never doing so. Starting to notice a pattern of confrontation, ego, and escalation among some of these people.
