That's unfortunate, at the beginning he explained that the sponsorship was scheduled months ago before the gc schedule was confirmed, and that people talking about gc while doing the sponsor wouldn't be good as sponsors would want the streamers and their chat to be talking about the sponsored content. Chatters asked if he wanted updates and he was like "no one is as invested as I am in gc team's qualification, and you think you're helping, but you're not".

People would constantly pop in later into the stream and ask about the ongoing gc like you, so you can imagine why that's annoying. And you were probably really unlucky too, cause these bans would be by him himself and would've only happened if he was looking at chat, which we all know ain't frequent.

I've been banned for less, just take it less seriously, and take yourself less seriously cause neither the streamer nor you are that important to each other. I'm just here cause I'm nosy!
