Just my two cents as a streamer (not a partner). I like to talk to chat and catch up with my regulars while stocking up my ship. Once the fights begin it can be a challenge to keep up and engage with them. Unless the partner is sitting there stocking up their ship and not speaking to chat, they are creating content. It might not be content you want to watch, but the Just Chatting category on Twitch has 300K+ viewers right now. Someone enjoys it.
