So I created an open-source Lemmy bot to reply to posts/comments with YouTube links with converted Piped links to preserve your privacy.
Piped is an open-source alternative privacy-friendly frontend to YouTube. You can watch the same content from YouTube without connecting to Google's servers.
I currently host the official instance, which is entirely run by donations. However, there are many community instances people can switch to in the preferences menu on the site. They are listed at https://github.com/TeamPiped/Piped/wiki/Instances
And I would like to add that one can download "Yattee" (Privacy oriented video player for iOS, tvOS and macOS), and add any instance from this list by adding its URL in Parameters > Instances > Personalized instance. It's really an awesome client.
