Youtube actually shows the breakdown by search request. 10% of the video's views came directly from people searching for stuff like "twitch view bot" in Youtube's own search feature, 2% of all views coming from people searching the exact phrase "how to view bot on twitch". The algorithm is directly responsible for a majority of the views still, sure, but that algorithm is heavily informed by the people who initially gave the video views from the direct searches and then went on to watch other videos on how to view bot on twitch (because the algorithm then steps in and suggests this video around those other videos). Also, he does actually explain how people are effectively now allowed to buy viewers in a way that Twitch condones -- specifically by paying to embed the stream on other websites -- so people who are looking at different options might actually be watching his video for a significant amount of time.
