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.
A couple days ago I found a service called Farside, apparently you can replace youtube.com with farside.link/piped to redirect to a random smaller Piped instance. It works pretty well for me, although sometimes I just use il.ax because I’m just lazy and don’t want to type that much.
