It's entirely different than using uBlock for youtube ads which reduces the amount of ad views for the youtuber which definitely reduces their revenue.

I presume these sponsorships are just part of the creator's video, no different than the regular content, and not like those 'real' advertisements where your video gets paused and the ad is embedded into different video player.

This is literally skipping by hand but just automated, I don't see a difference.

The reason the sponsors pay for this stuff is because people watch it. Systems which encourage widespread automated skipping of sponsored segments discourages their use in the first place and either eliminates a source of revenue for creators or escalates the arms race to embed sponsorships more and more thoroughly into primary content.
