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.
NewPipe works by fetching the required data from the official API (e.g. PeerTube) of the service you're using. If the official API is restricted (e.g. YouTube) for our purposes, or is proprietary, the app parses the website or uses an internal API instead. This means that you don't need an account on any service to use NewPipe.
So NewPipe doesn't use yt API and it never accepted its terms, so NewPipe is safe (from my understanding)

What about ReVanced? Should be safe, since it's just a modded version of the official YT app, right?
Unfortunately that's more likely a strike against them than in their favor
