I'm a native English speaker fluent in Japanese, recently moved to Japan this year. The one that really gets me lately is YouTube now automatically dubbing over content in Japanese that was originally in English. It's... so uncanny.
Yeah, that is a massive problem. This can't be disabled by the user, only be the channel owner. It's awful. The only solution is switching the YouTube UI language to English, to get the original English audio track. But then, presumably, all other languages would get machine translated into English. There is nothing one can do.
I recently found out DeArrow (an amazing extension to remove clickbait titles and thumbnails) also has an option to hide translated titles, off by default. But the extension you recommend can be used to force the audio track, which is very helpful.
