When the WBTS reads this they can see it as dollars and cents. 34 to 1. They will control parents with new methods of raising children to ensure new adults to control in the future. 34 is a target area and if you can weaken that mind with better brainwashing, the money is as good as in your pocket.
I see. So your fear is that the WTBTS will "discover" that some folks who are raised as JWs don't remain JWs as adults.
After the WTBTS "discovers" this by means of the survey's self-selected sample (the numbers are niether "representative" nor "generalizable" past the sample), the WTBTS will develop more brainwashing tactics to keep young JWs from leaving.
So, in your opinion, prior to this thread, the WTBTS was not aware that many "young ones" leave?
