Well, I’m still reserving judgment if this is for real.
If it is real, then I agree that some legal advice they have received is the best explanation, as with Bulgaria, closing the book study, and other presumably legally motivated actions.
That being said, just because Watchtower may make a decision for legal reasons, doesn’t necessarily mean it was a necessary, or even particularly advantageous change. They are clearly capable of making poor decisions which they believe to be vital or strategic, but which are in fact ineffective or even counterproductive. So if it looks and seems like a stupid change, then it might really be a stupid change.
Because I honestly cannot imagine in what scenario a religion gains benefit from removing reference to a spirit or supernatural power in their baptism. Unless they are going to systematically remove all references to the spiritual in all their activities, and quit calling it a religion, which is just absurd. Besides which, isn’t calling it “Jehovah’s organisation” just as strong a claim as calling it “spirit directed”? It doesn’t make sense on any level. But these are the people who think an overlapping generation makes sense, so there is really no telling what if any logic lies behind some of the decisions they make.
