YT premium is free of ads that Google serves. But most YouTube shows are funded by other ads embedded in the shows themselves. I wish Ad Blockers could remove them.

How hard would it be to implement an ad blocker browser extention to do it? Query an api endpoint with a video ID to find out start and end times for the ad and automatically skip over it. Allow users to volunteer to submit those ad times to build up the database. It would be limited to browsers, but it would still be something.
