The rapid change of tune from Fox is pretty embarrassing frankly, for any organisation that is even pretending to be a provider of news. There were plenty of sources who were calmly and rationally (and non-politically) saying in early February what was really going on, and Murdoch's idiots led the charge of people calling those early news providers panic merchants who were simply out to discredit the President.
Find some people who have researched the psychology of crisis management. Lesson number one is tell the truth in a brief and accurate manner. The worst thing in a crisis is mixed messages. For people who have studied the psychology of disaster response, organisations like Murdoch's are a disaster because they are opinion makers/regurgitaters rather than genuine news journalists. The good people at Fox filter any incoming information through their ideological and fundamental biases before spewing out the result, which generally is light on facts and heavy on propaganda.
You watch, as this thing develops Fox's people will start blaming other media sources for not having done their job and start claiming that they knew what was happening all along, and accuse the "other side" (whoever the hell they are) of politicizing this whole thing when President Trump couldn't possibly have done anything to stop the disaster that unfolds. It is very easy to slither into a new role of your own making when you are a greased up pig.
On the psychology of crisis management, it is interesting to compare our own dearly beloved leader over the last few weeks. He has gone from a blokey, she'll be right, "I'm going to go support my beloved Sharkies" approach, which played to a similar politicization of the crisis as Fox news, and likewise sent mixed messages and added to the crisis, to the last day or two where his messages have been more direct, strong (unambiguous), and somewhat more factual. I'd suggest that as it has slowly dawned on Scotty from Marketing that he can't slogan his way through this one, he has actually reached out for help, and some staffer has found someone at a University and asked for advice on crisis management.
