The 1975 fiasco was eerily preceded by a similar one precisely 50 years earlier, the 1925 fiasco. Recall that 1925 was the crux of the "Millions will never die" campaign with accompanying booklet and speeches. That hype had begun in the teens (see any similarity to the late 60's?)
When 1975 approached, it's understandable that the governing body must've been a bit nervous. It appears that they instructed their writers to launch a pre-emptive strike within the pages of the 1975 Yearbook of Jehovah’s Witnesses -- ... er, just in case 1975 didn't bear out what they had strongly implied.
It's clear from those 1975 yearbook pages that the Society hadn't changed. Again, instead of making an apology over what Watchtower publications had said about that failed 1925 prediction -- and more important, those sleight-of-hand phrases -- they made a conscious decision to publish a blurry recollection -- an obviously inaccurate one -- by a devoted, yet elderly, member.
". . .So, as Anna MacDonald recalls: '1925 was a sad year for many brothers. Some of them were stumbled; their hopes were dashed ... Instead of it being considered a 'probability', they read into it that it was a 'certainty', and some prepared for their own loved ones with expectancy of their resurrection." 1975 Yearbook, p. 146.
The '75 yearbook couldn't have solicited a better testimony about that disgraceful episode of times past. Here, the blurred reminiscence of this innocent elderly person would serve Watchtower's purpose far better than taking a few steps into the vast Bethel library to copy an exact -- yet more important -- honest reference from issues of Zion's Watch Tower.
Pre-1925 Watchtower issues had never stated the word probability in its writings -- that lone woman did it for them. By quoting this person, Watchtower skillfully and willfully endorsed her error, knowing it would serve its purpose -- that of perpetuating Rutherford’s cover-up. Oh yes -- blaming the flock for "reading into it" was Rutherford's invention. The 1975 Watchtower followed suit, preparing the modern flock into accepting blame for "reading into" what had been said about 1975.
Rutherford’s cover-up now became a Knorr/Franz cover-up. Clearly, this 1975 rehash turned into a well-orchestrated and pre-meditated lie.
New York Yankee's catcher Yogi Berra said it quite nicely, "It's déjà vu all over again".
