I agree with Phizzy
even if you bugged years of GB meetings it wouldn't cause an exodus, just a major response from the GB
hell, Ray Franz was a GB member that left and wrot a book and the BOrg is now at 8 million. But the response from the GB to CofC was massive and impacted the writing dept. for years, heck even to this day. I for one believe the Proclaimers book was a direct result of C of C.
if you take all the changes of the past 10 years and list them out they are ENORMOUS. the WTS has completely reinvented itself and the R&F are eating it right up. They're so horny over JW.org and big screens at the DC that nobody even notices the complete absence of any serious articles about blood or the slow depracation of 1914.
When blood is a conscience decision and 1914 is nothing more than the beginning of the "harvest of the wheat & weeds" these monumental changes will go almost unoticed over the lates released tablet app.
I think the entire GB being arrested and imprisoned for fostering pedophiles would be huge. Yes this would create solidarity among the hard-liners but for sure a LOT of JW's would go online and exit the BOrg as a result. Leaving only the most loyal committed dubs among the ranks.
But I guess if they can survive "overlapping generations" they can survive almost anything
