Placement of closed-captioning does not interfere with the viewing experience of folks without hearing loss. They didnt ask for it and always defaulted to "uncaptioned", as it should be.

In turning the closed-captioning ON to English, it is the loss of English (in non-English language movie) captioning when a foreign actor sporadically speaks in English. "Normal" English viewer would enjoy just the same; deaf and hard-of-hearing, not so much.
