PP - I suspect you are right but the JWs probably will soon be less than a footnote at the rate they are hemorrhaging members (and by that I mean countable bodies at KHs). Probably it is death by a thousand cuts, but the internet gets special mention for their woes. Finally the pandemic arrived and gave many chained-up members the time away necessary to wake them up - THEY WERE FREE! And they liked it.
I see photos of congregations in session and most have less than 20 people. There may be some on Zoom but they are NOT at the KH. Some will argue that they are growing, but they clearly are not. Numbers can be manipulated (remember Enron?), but photos and reports of empty congregation meetings tell the real story.
