Your first assessment was quite correct. Some has already become public, but, unsurprisingly, there's a lot more to come, evidently. And NBC execs had to know where Ronan Farrow's work would lead.
Personally, my takeaway from all that has come out is that my utter contempt for the entertainment and "news" media has been over-the-top much too kind. There's a tell-all book coming out by a female former Atlantic Records A & R manager that sounds like normal people will have to take a shower after every chapter.
