My guess would be only a fraction of people participate. I watch a bit of Twitch, but for me, the chat might as well not exist. (edit: that isn't to say how important participation and communication are for building a community, they are) Second, ads don't need payment methods. Kids and teenagers may not have debit or credit cards, but are a hugely valuable demographic that advertisers want to target. So as long as Twitch stays relevant to those audiences, ads will probably be quite valuable.
