My latest gripe: Youtube deciding to auto-dub language learning content that contains 2 languages so it contains only 1 language, so you can't learn the other language.
And thinking that auto-generated English is somehow a different language than English, so whenever a video only has captions in the 'other language' than the last video, it decides to offer captions in the video's original language, which I don't speak (yet), which is why I turned captions on in the first place.
This ties into an overall bias of Youtube against people speaking (or learning to speak) more than one language. Surely some of the developers speak more than one language?
