There are two answers. First, the algorithm obviously sucks. Maybe they have it programmed in a way that attracts other people to watch a ton of stuff, but it definitely doesn’t match your interests and personality. The second point is that as YouTube has changed how they pay content creators, they have disincentivized various types of videos. Depending on the content creator and the topic, it might make sense to have a relatively short video or possibly a quite long one, and yet it seems those are not getting the type of payment that they used to.
Another point that I have heard various YouTubers mention but I don’t know the details of involves how the algorithm will either hype you a lot or not hype you at all. Various channels used to get large amounts of visits routinely and then in a matter of 2 months those visits dropped to a few percent of what they once were. In other words, the algorithm appears to be very polarizing in certain cases.
Let us not admit to possible crimes on teh Internet. :-)
