I also greatly like the lack of human interaction in single player games. It is relaxing. Multi-Player is a different feel, more like a party, hence LAN-party, and I enjoy those if I am co-operating with a team which is competing against another team.
The commentary aspect of the game, if it is introduced, could be a solo experience too. It would be akin to watching TV. (Many people are turning away from TV these days, for many reasons.) Streaming is popular enough for Larian to build support for it into the game. I think that commentary needs to be included with that.
Think about why some people would point their browser at a BGIII stream. It is "the same story", so why would they repeatedly watch BGIII streams? What would the audience be getting from it? How would the views help BGIII itself?
It wouldn't help IMHO. I have watched twitch ruin 5e campaigns because players stop having fun and try to script for the audience.
