1975 - no light bulb
A generation is "2 overlapping groups" and can span 180+ years - no light bulb
Taking blood "components" is a sin worthy of eternal destruction, but taking blood "fractions" is A-OK - no light bulb
Your Kingdom Hall loan is forgiven, replaced by a never-ending monthly demanded payment - no light bulb
Dozens of branch offices closed, Awake magazine reduced from 768 to 48 pages per year, 100+ year tradition of Yearbooks abandoned, etc etc. etc. ad nauseum & infinitum - no light bulb
Why would "we're closing your Kingdom Hall, drive somewhere else" cause any such "light bulb" moment?
Because each of the other changes involve just accepting abstract changes or a reduction in what you are receiving.
Actually rearranging your life so that you can travel greater distances to make meetings involves you actively having to do something.
Plus it comes on top of all the other changes you mention. So there is likely a cumulative effect as well. For many the additional ask will surely be the straw that breaks the camel’s back.
