The reason this keeps coming up is that people were hurt by it. Anyone who made a choice in life at the time based on the false expectation (which was invented by and fostered by the Watchtower organization and its representatives) was hurt. There are precious life resources that are spent in one way or another. Some who decided to not get married and have children are now facing their elder years without the joys of children and grandchildren. Others missed out on careers they would have found fulfilling. Others decided to not pursue something they had a great talent for, such as music, poetry, etc and instead spent those years knocking on doors chasing a false dream.
The WT society earned my contempt when in my twenties, I realized that my decision to not go to college hurt me, and it was all based on their false beliefs.
