Taking those videos off YT will make things worse in terms of the inequality of deaf people. YT at least has an ability to automatically generate subtitle. It is not perfect, for sure, but is still better than nothing
Hi, this statement is objectively, entirely, incorrect. I assume you are talking about English. I have used YouTube's subtitles on Berkeley's lectures, and they are almost entirely correct; the errors that are present do not impede understanding. E.g. in a math lecture if a lecturer sees x with a subscript zero, and they say "x naught", YouTube captions might say "x not".
I believe it was explicitly ruled in the courts that Youtube's automated captions were not up to the standard required by the ADA. Not sure where I read that, but it was probably on HN somewhere.
