Google successfully killed privacy-focused YouTube frontends like Invidious and Piped.

You were able to watch YouTube without a Google account in a privacy-respecting frontend. You could still subscribe and create playlists as normal, but without all the Google's tentacles looming over you.

Piped was particularly feature-rich, I found it to be way better than the default YouTube experience, and the mobile app was simply amazing, with (21)million features, customizations, and good UI design.

Sadly, nothing works anymore. It's been months, no fix or workaround has been implemented. Public instances are going offline one by one, my hope is lost.
