Rossman is right about things in the case that Google is targeting only adblock users (whether this 5 second delaying thing is this type of action or not)

Google can try all they want to throttle or restrict ad-free experiences as much as we’re free to try to get around them, and using YouTube without ad or tracker is not compensating them so they don’t owe us anything. Anti-competitive practices, invasive tracking and things like that we can target Google for doing.
