Removing moments is a momentous mistake and would be a sad moment in the history of Twitch. Keeping moments encourages viewers to stay around and leave the stream up even during moments they aren't actively watching because the streamer might give out a moment at any moment.
Moments also let viewers show their support for streamers in chat without having to have a sub at the moment. With the greater focus on momentary ad breaks, encouraging viewers to stick around for moments gets more viewership for the ads as well, which gets the streamer more money every moment they play ads.
