Yes they praised witnesses who had sold their businesses, houses etc. in order to preach more. When 1975 came and went with out Armageddon coming, for a few more years they still had a lingering hope. But the reality kicked in when the money they had gotten from those sales ran out.
There must have been many that wrote to the society about this. The society countered by mocking those who had followed their encouragement. I remember an assembly talk where the society said "there were those that in thinking that Armageddon was soon to come, ran up their credit cards thinking they would not have to pay it back. Hahaha." Then they chided the ones that had sold their houses etc. by saying "we aren't serving God for a date are we?"
Lately, they had a video that called the sincere followers in 1970's "spiritually weak" because they looked forward to a date. Yet it was the WT that published dates.
I was there in 1974 at a convention and remember the talk given on Sunday's keynote address.
"It has been 6,000 years since Adam was created. How much longer after that did Adam finish naming the animals? Not long (because supposedly there weren't as many animal "types" to name) How long after that was Eve created? We don't know, but certainly it wouldn't be long after Adam noticed that the animals had their mate, that he would feel lonely. How long after Eve was created, did they sin? Not long (because otherwise Eve would have gotten pregnant) So Brothers and Sisters, whether it is days, or months these things occurred, we know it won't be long for God to act and bring an end to this old world."
Of course, this isn't word for word, but it is how I remember it. The whole stadium was silent at the end of this talk.
The last push the society did like 8 years ago about the world being so close to the end, the owner of the sign shop I worked in, sold the business so she could pioneer. So they are very persuasive in getting people to follow their directions.
