Could you see the GB deciding that DF/shunning would only apply to those persisting in their "sin"? Or, only to those actively speaking against "The Truth" (or the "glorious ones")?
I do not think that relaxing the position on the shunning of those who no longer persist in their sin or who do not actively "oppose" the religion would have much of a harmful effect on the Organization.
Anything and everything there is that is negative about WT/JW's is already at the fingertips of anyone with a computer or a smartphone. Most JW's are ignorant of the negative stuff because THEY WANT TO BE IGNORANT OF IT. For most of them that attitude will never change.
