In any event, more recent coverage:
suggests that the problem was some slings made by Infantino. I don't know that I've seen these specific slings in use, but if I haven't, I've seen something just exactly like them, and they looked a lot like carrying the baby in a big, plushy handbag. Not precisely attachment promoting and also a little creepy looking. Apparently Consumer Reports pushed on the CPSC and there is, furthermore, a lawsuit in progress.
I don't know that there's a moral here. If there is, it is probably something depressing like, if the product enables you to sort of forget you are toting a baby around, it might result in problems.
