Anyone who’s been using privacy-respecting frontends for some time will recognise Piped. A YouTube frontend with no ads, integrated SponsorBlock, return dislikes, and a customisable UI.
Piped also allows you to subscribe to as many channels as you want without ever logging into a Google account. You can export your subs list from YouTube and import them to Piped seamlessly.
If you’ve never heard of it, give it a glance at https://piped.video. For more instances, check here.
I use it for about a year new. There are a few hiccups now and then, but you can just switch instance. That’s why I recommend using Libredirect with it. If you have trouble with an instance just ping the instances in Libredirect and chose a new one. Backup your preferences from the old instance and import it to the new. Your settings and subscriptions are available again.
