I think he is talking about other revenue streams that most large creators use. Such as ads the creators place in their own videos, merchandise, and direct payments (Patreon, subscribe star, etc).
Op suggested advertising hasn’t been the revenue model for creators in 10 years which, upon further research is plainly false. He completely made up the claim in an effort to justify his use of ad block.
By blocking ads you’re harming content creators, it’s really that simple. Blocking ads on indie content is nothing short of theft as far as I’m concerned.
