Google could certainly detect when sponsored ads start in YouTube content and skip them to honor their "no ads" agreement with YouTube Premium customers.
That, or they could pay content creators fairly so that they don't have to shill for NordVPN in every video they release.

SponsorBlock does it, and Google could make it part of their policy for content creators to mark sponsored ad segments in their videos so that they can be skipped.
