Aw man. This is how I watch YouTube videos :(
I love these privacy-friendly front ends for big tech websites. I guess it was only a matter of time before Go.ogle started fighting Invidious/Piped instances.
If you haven't already checkout the plugin called "Privacy Redirect" for Chrome/Firefox. There's also an android app version called UntrackMe (I think?). They basically intercept YouTube/Twitter/Reddit links and redirect them to privacy-friendly instances.
