you want YouTube to interfere with the content of videos even more than they do now? how much assurance do you want that a video doesn't have any sponsorship? a human viewing each video before it goes on to the CDN? affadvit from the poster that they didn't receive money from any VPN company before mentioning a VPN? why are you blaming YouTube for the poor quality content you're choosing to watch, instead of not watching it or blaming the creator?

YT has nothing to do with them and imo there's no reasonable policy line to draw between the many forms of native advertising with their varying levels of invasiveness, nor should we really want YT to be the arbiter.

You also have never been required to watch them! I just right arrow a couple of times but if you want it automated you can just use SponsorBlock and feel content that in exchange the creator is getting extra revenue from your Premium subscription.
