You might have noticed that the author started the blog post explaining themselves:

  Like 6 years ago I wrote a WebRTC SFU at Twitch.
  Originally we used Pion (Go) just like OpenAI,
  but forked after benchmarking revealed that it was too slow.
  I ended up rewriting every protocol, because of course I did!

  Just a year ago, I was at Discord and I rewrote the WebRTC SFU in Rust.
  Because of course I did! You’re probably noticing a trend.

  Fun Fact: WebRTC consists of ~45 RFCs dating back to the early 2000s.
  And some de-facto standards that are technically drafts (ex. TWCC, REMB).
  Not a fun fact when you have to implement them all.

  You should consider me a Certified WebRTC Expert.
  Which is why I never, never want to use WebRTC again.

I think that they've done more than enough of 'trying the normal way' to be warranted in having an opinion the other way, don't you think?

Yes,agreed. I also found it apparently obvious that they have proven their experts worth on this subject matter. Many times, over and over.

But ChatGPT said …

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.
