BTW, I'm aware that yt-dlp is against Youtube's terms of service, but in America, the right to timeshift a broadcast was well-established in the days of VCRs by multiple court precedents. It has never been tested in court whether that right would also apply to Youtube and downloading videos from Youtube for the purpose of timeshifting, but IMHO it would apply, so I'm doing it.

Also, while Youtube claims that adblockers are also against their Terms of Service, if you actually go read https://www.youtube.com/t/terms you'll see that their claim is not supported by the actual language of their ToS. They forbid you to "access, reproduce, download, distribute, transmit, broadcast, display, sell, license, alter, modify or otherwise use any part of the Service or any Content" without their express permission. But adblocking is not altering the Content of the service, it's blocking certain videos while letting other videos through. If there was a service that detected "here's a word from our sponsors" parts of the video and removed them, that would be altering Content. But the ads are not part of any given video, rather they're external videos inserted at certain points into the video you're watching. Selectively blocking video A while watching video B is not forbidden by any part of Youtube's Terms of Service.

So go ahead and use uBlock Origin with a clear conscience, unless you can find the part of their Terms of Service that actually forbids blocking certain videos while letting others through.

This exists and it's called SponsorBlock. It automatically skips past sponsored segments. Debatable if that is altering content though
