Right but they also state they have never implemented TURN which IMO is a marker of WebRTC expertness. (I haven't btw, just the WebRTC experts I know absolutely have written or worked on at some point a TURN implementation)
It's not that strange. TURN has two main use cases: peer-to-peer when no viable direct path can be found and working around very strict firewalls. Based on the author's experience the first isn't relevant and the second isn't much of a concern for Twitch and Discord. For the latter case HTTP/3 is helping make TURN unnecessary because you can, as the author observes, run UDP over port 443.
