Here is the Watchtower quote that the declining number of anointed was proof of being in the last days.
(W 1-15-2000 p13) Subheading “Six convincing lines of evidence [that we are in the last days]”
18 "Sixth, the number of genuine anointed disciples of Christ is dwindling, though some will evidently still be on earth when the great tribulation begins. Most of the remnant are quite elderly, and over the years the number of those who are truly anointed has been getting smaller.”
At that time (year 2000) the number of anointed (partakers of the emblems) had been declining. Now the number is increasing quickly, as shown by the Society's own count.
