Post correction and retraction

Apologies!  I took down my post based on this tweet, which upon further reflection struck me as premature.  Does anyone have actual word from the would-be co-author as to what happened?  Note that sometimes individuals don’t want to be co-authors on particular papers, especially if they are working in the private sector or for multilateral agencies.  They have to go through the time-consuming refereeing process, and they are responsible for the final results in the paper, possibly with no professional rewards for the publication itself.  The employer may need to be involved with clearance, or the employer may not like the results in the paper.  I don’t know whether that is what happened here, but so far it seems that nobody knows.  If I learn more of substance, I will update you all.
