I don't use my twitch account ever anymore but I don't think there is really the same concept in twitch. I think most people probably watch 1-2 of their favorite streamers since watching streams is already such an incredibly time intensive activity. The most active someone can get is probably clipping short videos and curating clips.
I don't think you lose access to any of this when you unsubscribe, I think you just start seeing ads again when watching the live stream.
