Me watching a sponsor segment isn't going to make any money for the video creator. They're being paid by the sponsor to place the segment in their video; there's no way for the sponsor to track who watches it. The segment is just a waste of my time.
This is separate from YouTube itself tracking who watches the video, and for how long (and if they skip any), and if they watch any ads, and then giving a bit of money to the creator for the ad views.
