It would be easy to have missed the changed WT view. The article makes absolutely no mention of the fact that this was a change in view.
One paragraph talks about how some people might sort of push an elder into thinking he is a head over sisters when they come to him looking for him to make decisions for them. But the reality was that the WT held brothers to be the spiritual head over sisters. The sisters would naturally think that they should go to the elders for direction, just like a child might go to a parent for direction.
Someone of Reddit also commented on the fact that there was a box in the study article describing the role of the GB. But that it was rather noticeable that the box did not point out the obvious - that if brothers are not spiritual heads of sisters, then, the GB are not heads either.
The whole article was curious about what it didn't point out. It was like it wanted it to appear that this was always the case.
I might add that I went to their online library to check the Publications Index under headship. Under headship within the congregation they have the Feb 2021 article referenced. No other references are listed. Yet, the last link in my first post of this thread is to a thread that has literally dozens of WT publication references to the old headship view.
I wonder if they've scrubbed the Index of the old viewpoint?
