This is my uninformed guess at the reason these chronology articles appeared. Just a guess, nothing more.
Mr Furuli has developed a following among many Witnesses, almost a personality cult. As the saying goes, if you tell a lie often enough and loudly enough, it becomes truth (that's how the WTS system works, anyway).
Over time, some of these fully convinced Furuli adherents have made it into areas where they were able to wield their influence on the Writers. At some stage, Furuli would have become involved.
I have a feeling that the November issue was delayed by a few days. If that is correct, this suggests difficulties over certain details. It will be interesting to be able to know the internal discussions, who the dissenters are and what they had to say. I would not be surprised if some of the questions raised in this Forum were also raised internally, such as "Why bring up the subject?"
Just wild guesses. Nothing more.
