People don't want to pay (help) people they don't like. YouTube ads do not feel fair, they feel manipulative and unethical. It's expected that most people wouldn't want to willingly engage with that kind of asshattery.
Contrast that with platforms like twitch. I'd say the average twitch viewer (that interacts with streams/chats) has a slightly negative view of Twitch. But many will still willingly donate dozens of subs to streamers they like. This removes ads for other people, not themselves.
People think YouTube is greedy and untrustworthy. Why would you willingly feed that machine?
