Can someone create (or does it already exist?) an app that plays the videos in the background, remove the ads and then let you playback the whole video ad-free? Sort of like you did back in the VHS-days....
On Android, there's Newpipe which doesn't run ads, and Newpipe x Sponsorblock which clips ads out from the video. On desktop there is FreeTube which also has SponsorBlock you can turn on.
