That isn't clear. Some earn money from ads of various forms. Some earn money from patreon like things and the youtube views are loss leaders. Most are not earning enough money from ads to care (generally 0, but sometimes a few bucks).

Even if you earn money from ads, view count is only a proxy at best. Youtube seems to track ads seen not view count (payments from youtube have not changed). Other ads track effectiveness of the ad, and viewcount is only a proxy - if youtube changes the count it means that the constant applied to viewcount in the formula changes but otherwise the payment is the same.

Thus if you get significant money from YouTube adds you care about ad blocking. None of the others need to care (they might, but it could go either way how they feel)

What videos you see on YouTube really varies from one person to another: I have one browser where it shows me predominantly videos with titles like "Why Brand X has lost it's way" or "Why the Y industry is broken" where X could be a fast food chain or a game studio and Y could be housing, video games, private equity, etc.

That kind of creator expresses a lot of negativity towards YouTube, as X is frequently "YouTube" or "Google" and Y is "Big Tech", "Social Media", etc.
