No. Science very very rarely changes. The confidence in the possible explanations is what changes. They communicated low confidence information with high confidence. The trust was destroyed with, what appeared to be, a concerted effort to silence those that accurately communicated the low confidence, or presented other equally possible, and far too often eventually-correct, understandings. I think this covers all the other points, above.

"We're sorry millions of you are dying, but we got nothing for ya'" may be good science but horrific politics.

That’s, obviously, nonsense/hyperbole. I would suggest looking at the communication in Germany for a good example of science communication.
