No. It's not criticism. What they're saying is that the video was shot with a default that a sighted person could understand, because any blind person would naturally have their speed set to much higher than that.

It's like how in videos that teach people a foreign language, everyone speaks slowly and uses simple words, even though native speakers don't talk like that at all. The GP is simply saying that an actual blind person would be way more efficient at it, but they made the video with inefficient settings so sighted people could understand what was going on.
