It depends how well you know the other person. Is the one-sidedness actually just social awkwardness because of unfamiliarity and not wanting to appear too "forward"? Or is it the person's baseline way of speaking? If after getting to know someone and finding out it is their baseline I tend to limit association with them as it's too draining, but I will try to let the person know what they're doing first as there could be a chance it's just serial thoughtlessness on their part. If they "get it" great if they don't I will just let nature take it's course as people who are like this usually don't like having their conversation style pointed out to them and the relationship dries up all on it's own.
I do think the internet has changed and is changing the way people communicate online and in person. I also found most if not all JWs are like this, you could not have a to and fro conversation with them. The conversation style of JWs was to talk about or talk at but not talk to. While they talked about other people behind their backs they somehow considered it rude to talk face to face with the person about the very things that they talked behind their backs about even if the person themselves brought it up. It was weird. I'm still trying to figure out how to communicate after leaving the borg.
Why were you asking CoCo are you just curious or is it work related?
