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”.
I guess in theory yes, because sponsors would eventually notice a drop in people spending money through the creator.
Personally, I haven’t and won’t ever use a product just because my favourite entertainer was paid to say its good. Before SponsorBlock I just manually skipped or tuned them out anyway, so I never counted in the first place.
That implies that the person skipping the ad would have purchased in the first place.
Ads are like Nigerian Prince schemes. They are targeted at the people who are willing to engage. Skipping them is no different than ignoring them.
