Yes, business.

This wasn't business. There were no profits to divert into making better subtitles.

And the ratio of effort between making a recording versus making a recording and then manually subtitling it is completely out of whack compared to the ratio you have in full produced works. There's a reasonable level of accommodation, and the reasonable level is below a doubling in costs.

I'm someone that would significantly raise the subtitling requirements on youtube if I could. But in this case I just don't feel it.
