It sounds like you might want to read their technical report. That’s neither anecdotal nor a single point, and it showed a pretty large gap in engineering leadership with numerous areas well behind the state of the art.
That’s why I said it was compatible: both these former employees and their own report showed an emphasis on shipping rapidly but not the willingness to invest serious money in the safeguards needed to do so safely. If you want to construct another theory, feel free to do so.
In other words, it confirms our biases and we're willing to accept it at face value despite there being only a single anecdotal piece of evidence.
