I don't think anyone has mentioned that the February 2021 Study WT (p. 15, 16; par. 8) changed WT's long standing view on headship within the congregation. WT used to view all baptized males as being the head of all baptized sisters.
This view led to such absurdities as a sister having to wear a head covering on a Bible study because her baptized 10 year old son was sitting in on the study with her.
As might be expected, the study article avoids any mention of the long-standing past wrong view of the WT (along with all the embarrassment that may have accompanied that wrong view). I posted about this on this board a few years ago but I wasn't able to locate the post. But I did copy the post onto another board. It can be found in the link in this post (off-site).
For reference, this thread has numerous references to WT publications showing WT's past view. I linked to it in case these references disappear from the WT Publication Index.
