I watched the stream on YouTube and the audio was kept as is. I doubt it would be the same for the VOD later but, couldn't Twitch do the same?

Also, isn't Blizzard or Twitch breaking their ToS by simultaneously streaming on Twitch and YouTube?

It wasn't just Twitch's platform: it was Twitch's own channel /twitchgaming. On YouTube, Blizzard just streamed it to their own channel, and they've surely cleared the rights (for now).

I don't believe there are any ToS covering simultaneous streaming on Twitch and YouTube for either service.

Partnered streamers sign away co streaming rights to become partners and get those benefits.

For most streamers, they want a community and costreaming does the opposite of that

For super large events having a split works. Large events aren't usually partners in the typical sense

Even if there was a tos issue, I'm sure blizzcon will be on their own contracts for this kind of stuff
