Maybe frustration with YouTube somehow drives more engagement, so you'll go looking for new content and stay longer -- like how shops rearrange things to expose you to other goods and so increase sales.

Maybe YouTube have found that rewatching items drives people to annoyance with the adverts and gets more revenue?
