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.
Honestly, I pay for YouTube Premium but I still use Revanced and NewPipe for the extra features. Why can't they just leave me alone?
