I think the author realizes they don't have a full picture. They never claim to know all the facts. They even say in so many words that Uber has been unwilling to share it's internal corrective actions or have executives discuss with investors the sort of issues they're dealing with. There seems to be a veil of secrecy between management and these particular investors. I don't think being a founder should mean that once the check clears your free to do whatever you want and answer to nobody. I don't think that's a very common arrangement. These investors are looking for actionable steps that Uber is taking to improve. Not a one-size fits all band-aid PR statement or middle-management meeting.
