As in, would the channel be losing out on money? Because I don’t want to take away from small creators if there is a retention rate for viewership of that exact segment, but I would prefer to skip any of the “but first check out this shitty mobile game”.
As far as I know sponsors have no access to data on how many people watch their segments as opposed to whole-video viewership, unless they force the creator to disclose it which I doubt happens basically at all. Creator gets paid upfront and a kickback for using their link, not for you watching an in-video ad itself.
