Earlier quoted context omitted.
And I'll leave this here: https://sponsor.ajay.app/ This also skips the sponsored parts of the actual videos ("this video is sponsored by skillshadow raid vpn,...")
I think this kind of add-skipping is worse. It is 'stealing' from the content creators rather than youtube. Besides, these ads are not based on surveillance capitalism but much less invasive old-school methods. Finally, there is much easier recourse against these ads. Don't watch content creators that have annoying adds. There are not many alternatives to youtube, but there are many alternatives to any given channel.…
I'm not so sure, from what I understand these creators are typically paid upfront to embed the sponsorship in the video and they are given some promocode or url to present to watchers and that's how these sponsors track engagement. I don't think they check the watch time or the skip rate.
