I don't think anyone has commented along this line yet, but I think I know EXACTLY what they are doing. The current and younger generations of JW's are in what is some ways an on the surface kinder and gentler organization. They WILL be on the internet. They will stumble across things, and hear things, that they will wonder about or don't sound right.
WT has been systematically re-writing its history for the current followers, and the younger ones still around. If you control the narrative, and give just enough, with a whitewashed explanation, you may defelct people.
Example. Lets say you are a 20 something online, and see something about 1975. You have never heard of it before, so you ask or research it. You get a lot of information, and you might in fact see where something doesn't add up. Now you know something. But.....if you have already seen this video, maybe you just say to yourself..."ah those crafty apostates. I already know about this, and it was a few bad eggs. I'm going to endure"
That is their goal. Guaranteed.
