Like, if you are releasing financial documents and a large entry is "HIDDEN POORLY INTERNALLY LABELED ACCOUNT.", it is hard to explain that without getting into outright malice or negligence so extreme that it is difficult to differentiate from malice. Even rudimentary reviews of their finances would have highlighted stuff like this, and they clearly had money to pay people to help them do it.
