I'm a bit embarrassed to admit that I just discovered FreeTube. It's a desktop YouTube front end for increasing privacy (Goog tracking) and removing Ads. I've been using NewPipe on mobile for some time already. Check it out if and don't look back. It's open source and excellent freedom tech. Export your subscriptions from YouTube and import into FreeTube and presto! you're in business. =) https://freetubeapp.io
