KH3's "commercial settings" rule

A while ago I asked about VOD mutes for KH3 and learned that, at the very least, enough of the VOD audio will survive for me to warrant a stream.

And then I checked the streaming rules for KH3 and read about the "You're free to stream this game in a non-commercial setting" rule. I know that you can't stream the game to listen to the music, but doesn't streaming it on Twitch, even if for gameplay and commentary, count as a commercial setting? Yet I see people streaming the game here and there. What are the rules for things like this?
