Peer to peer Livestreaming is much easier than storage + streaming, because everyone is online at the same time, and can restream to each other using webrtc. If someone drops out, those listening to their stream can join someone else. It helps the livestreamer save money and not have to rely on Big Tech platforms ingesting RTMP.
