I block all advertising myself, but sponsors I think are ok. The creator can control who they sponsor with, they can write a funny ad skit that is entertaining (the best ones I have seen are the ones by squishy boi) and the creator gets paid directly without fucking us with an algorithm.
I'm happy to watch those kinds of ads as I know the creator is getting paid from them, and e.g. YouTube isn't taking a cut.
I feel like this is one of those multiverse branch moments where Skynet is created.
