There's an "if a tree falls in the forest" version of "if the viewer leaves the room" at which point has a theft still been visited upon the broadcaster? The business that paid for the ad?

In a newspaper if I skip over ads with my eyes do you think I've marginalized/pirated/stolen from the business that paid for the ad? They paid for placement and not an impression. I'd argue that if YouTube presents the ad and my browser/app/whatever skips it then YouTube satisfied its obligation and that's where it ends. The advertiser, knowing full well the limitations of the access mechanism, made a choice to throw money into this version of the attention economy. It's obviously worth it to them or they wouldn't do it, or haven't made as careful of an economic decision as I would imagine I suppose.
