I don’t know for sure if it was ever a thing in the USA. A cursory search only showed mention of Europe offering that repair. I didn’t even bother checking and just went straight for the hall-effect replacement sticks when I had joy-cons that drifted, probably a bunch of other people in that same boat.

IMO, the profits from this would still come even if they offer repairs. I’d venture to guess many out-of-the-loop parents would just buy the replacements ‘cause they probably think their kid is abusing it somehow. The good ol’ “sigh 'n buy” phenomenon to keep the kiddos entertained.
