Twitch "permanently" won by injecting ads directly on the feed, right now best you can do is sneak swap the small resolution version that stay on the side until they also removed this.
Actually the modern vaft script can completely bypass ads and has seen minimal changes for well over a year. Twitch gave up because most people, even the tech savvy ones, don't know about the solutions anymore.
