when I did attend in the mid 80's, early nineties we were like a social/religious organization. The various clicks would always have something going on like concerts, plays, and weekend trips to varied places. "Friends" from around the circuit would call us the party animal congregation. The CO eventually discovered we were having too much fun and had the elders present a Local Needs Talk to put a stop to us from making too much merry. At that time our congregations had the highest number of publishers, pioneers, and averaged hours per publisher, magazine placement and meeting attendance in the circuit.
It seems that most places experienced that same thing. It happened where I was.
The JWs as a religion and group of people had finally kind of found itself. It's members were starting to become a united group, not just in the rituals of the religion but in everyday life. JW community was becoming a reality. But the WTS didn't want that. It wasn't about creating a community of like thinking or believing worshippers of God, it was about controlling the masses to keep them doing the bidding of the organization.
They were afraid that if the brothers got together too much away from a regimented program they might start revolting or something, that's how paranoid or scared they were. They didn't realize that most JWs just wanted to have fun with other people who believed the same way. If the WTS had realized that, they might be in better shape today with fewer defections.
Once they started dropping the iron fist of oppression on people, the friends weren't as happy. The worldwide brotherhood wasn't so brotherly anymore. People started questioning things on their own. In fact, it would have been better to allow the friends to associate more freely because a happy dub is a controlled dub. Once they were isolated, it gave them time to ponder on things. Once they were left alone to their own devices, they could secretly search or question and not have others look down on them.
Since the big crackdown of the early nineties on gatherings and parties, more and more JWs are isolated socially and have become unhappy. An unhappy dub is a questioning dub. And a questioning dub is eventually going to stumble onto something that he can't ignore and will become an ex-dub.
