The company’s team clarified that their terms prohibit third-party apps from disabling ads, as it denies creators their due reward for viewership. Although the announcement did not specify any app by name, it’s plausible to presume that third-party YouTube apps such as NewPipe, YouTube ReVanced, Piped, and others might be implicated.
Still dont know what the big deal is, libretube and freetube still work fine. Same with firefox and uBlock.
I use Revanced. Out of curiosity, I tried going to youtube.com on Firefox + Ublock origin on my Samsung a70. Full screen, “double tap to forward 10 seconds”, “double tap to back 10 seconds” and captions work.
