It's a familiarity thing. Sighted people are used to a manner of communication that includes visual cues, and people always prefer what they're used to. I also find that people who are used to visual in-person communication also dislike videoconferencing because they can't see things like when another person is crossing their legs or tapping their foot. Whether any of that is actually beneficial is another question entirely. Personally, I have an easier time concentrating on the conversation when it is audio only.
