But does Furuli explicitly state the reason for this alleged conspiracy ?
As I said a few posts above:
Furuli doesn't give any plausible motivations for the modern day tampering of this tablet other than either just to create a forgery and mislead people, or to correct the year figures to agree with the 'accepted chronology' (p. 108, 113-115, 137 [3rd revision]).
There seems no good motive for what is claimed by Furuli.
He presents nothing convincing as to motive. Speculation. Muddying the waters. All designed to further undermine the trustworthiness of 'worldly' sources (that disagree with WTS dogma) in an already suspicious JW mind, AND as you said before, he can do so without legal backlash because those he implicates in the (hypothetical) forgery are dead.
