People commonly defend this practise with "But the audience isn't meant to understand!" or "It's inconsequential!", neither of which actually address a) their assumption that the [ideal Anglo] audience wouldn't understand, or, perhaps most crucially in the context of CCs, b) that this is a failure of accessibility. A hearing person who speaks that "foreign" language will know exactly what's being said. A deaf or HoH person – the people CCs are primarily intended for – who speaks or reads that language should therefore have the exact same opportunity to understand. It very much feels to me like an assumption that we deaf and HoH people couldn't possibly understand any language but English, so there's no point in getting those languages transcribed for us. I hope it goes without saying how profoundly audist that sentiment is.

There is also, I think, a profound misunderstanding or ignorance of Deaf culture at play. Which is to say, CCs in English-language media are written with not only the assumption that the audience will be native English speakers, but that all d/Deaf and HoH people speak English as their first language, so all other languages are as supposedly foreign to them as they are for hearing people. But sign languages are their own distinct language. BSL, ASL, ISL, AusLan, NZSL etc ≠ English (and are indeed different from one another), LIS ≠ Italian, JSL ≠ Japanese, and so on. So, if you follow the captioners' logic to its natural extreme, all non-signed dialogue is "foreign" to many d/Deaf and HoH people and should therefore be labelled [speaks foreign language] / [speaks English] / [speaks own language] / etc. – which is, obviously, a terrible idea that perfectly highlights all the biases implicit in closed captioning.
