It’s funny how you put all the blame on the users and none on the people that run the site. They fail to pay creators properly, fail to protect them from copyright claim abuse, and all the while they expect those creators to keep making content to keep their site relevant. It’s going to come crashing down eventually.
Also, in matters of taste the customer is always right. If people are so fed up with ads that they adblock en masse and/or leave, then youtube are the only ones to blame.
