They are doing this to make access more difficult.

With transcripts you can alt-F and search for key words, then read or watch the video for specific information.

With videos only you have to A) invest the time to watch that human stroke babble on incoherently and try and hear key words, so you can then rewind a bit and relisten to the relevant parts or b) have a software make a transcript for you.

And fuck deaf people I guess.

Why would they do that?
