I think you're being unnecessarily adversarial here. Sponsored ads in videos are everywhere, and well delineated. Third party tools exist to skip them already -- and YouTube already has the data on where they start and end. They even show them on the timeline, although they call "end of sponsored advertisement" "most replayed"… presumedly because of everyone skipping the ad, losing their place, and then having to ste…
Would it have a negative impact on the businesses who promote those videos? Yes. If it's a negative impact on the businesses who promote videos, how can you say your idea doesn't impact content creators?
Promoted businesses currently pay based on (an estimate of) the number of views that the video will get. This would trivially adjust to paying based on the number of views that the sponsorship within the video gets -- that's why I mentioned the requirement to make this available through analytics. If the cost per view stays the same for sponsors, they're now paying for a self-selecting audience of people who are not actively bothered by their ads. (I doubt I'm the only person who, if I as going to pay money for a VPN, would choose literally anything other than Nord VPN just as petty "revenge" for how much of my life they've wasted.) If this slightly-reduced audience does not sufficiently eat their marketing budget, they can find new creators to sponsor.
For the content creators, presumedly the target amount paid directly per skipped ad would be chosen to slightly exceed the expected payout of showing the ad. This is the same conceptual model Premium uses today. So even though the sponsor may be paying them for a 9.5 M view video instead of a 10 M view video -- the payout should more than cover the difference.
I agree that these marginal wins run into systematic concerns if more than, say, 5% or so of users start opting out of embedded advertising this way. But besides being incredibly unlikely -- what would it say about the business model of embedded advertising if 5% of YouTube customers were willing to pay to avoid it!?
