Most of the points are mis-leading, especially the Location-Sharing one... It looks like FB and WA can't see our location, which is totally wrong. They actually mean that the location shared in chat can't be viewed by FB (which again is doubtful, imho). Naturally, if none of chat data is viewable by FB, then the Location shared in Chat can also not viewable for them...
Nothing special... This damage control measure is just FaceBook being FaceBook...
