I can't be bothered to use YT anymore with all the ads. They're basically interactive, on-demand, corporate TV monetizing other people's content and nothing more. The world needs a co-op video sharing app and a microblogging app.

The only "ads" you get will be the ones the video uploaders encode directly into the video itself. Plus you can watch using whatever playback software works best on your system, instead of the rather feature free JS player youtube provides.
But it seems likely to me that YouTube will eventually start embedding the ads more inextricably into the video streams while downloaded. Especially as more people use tools like youtube-dl/yt-dlp to circumvent ads.
