I think they would be making a big mistake if they cancelled or just restricted the Zoom meetings to the elderly and infirm.
I was reading posts on Reddit about how the religion can’t get people to come back. In my opinion as an observer, it was the two plus years away from the meetings that did the most damage to the religion.. In that time, people got ‘deprogrammed’ and got their minds back.
Let’s not forget that people were stressed out during the pandemic: some got sick, some lost jobs, etc. Also, people started to notice little things and some important things: like how important time is. Maybe they didn’t see the sense of all the meetings in the JW religion. Like why can’t they have one meeting weekly like other religions??.. Maybe people resented the level of control and intrusiveness into their lives and were glad to be rid of it. Maybe they came to see this wasn’t the ‘light load’ Jesus spoke about!
Even if some JWs do trickle back, I don’t believe things will be like they were before the pandemic - and even then the numbers were decreasing!
