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.
Sort of true, except YouTube. I watch almost exclusively YouTube few hours every day. If it opens by mistake in a browser, it is totally unwatchable with ads inserted even in short videos. I hope reVanced will manage to avoid detection somehow, otherwise it is quite hopeless. Yes, I can pay for premium, but the app will be full of stupid crap and no gesture controls.
There is also newpipe
Does it show my subscriptions, etc?
No, it does not access your account at all and stores subscribed channels locally within the app. But there might be a way to transfer your subscriptions over if you can find a way to export them from your youtube account.
You can def export your subs. I did it when I set up freetube originally. So it should just be a question of if the other program will import them.
