I think Prof Francois Balloux, infectious disease epidemiologist, summarized it well [1]:
I'm not convinced there’s a villain among the PO authors, but just a series of cock-ups and poor decisions, aligned with, and fuelled by, bad incentives, eventually engulfing everyone in its wake.
It remains an embarrassing institutional failure, however we look at it.
I disagree with those who try to rationalise their content and pretend that the authors changed their mind as they followed the science (sigh).
There was never any new real evidence that could have triggered a change of opinion in that time period, anyway.
The charge that the final version of Proximal Origins in Nature Medicine does not accurately reflect the PO authors’ doubts expressed in private feels fair to me.
