> No, this was some Apple-internal mechanical engineering group trying to design the best extremely thin keyboard they could, but getting bitten hard by a mismatch between reliability in a prototype vs. full-scale factory production + poor estimation of reliability in a wide variety of contexts over a longer period of time

Okay, but...what caused them to try to make a keyboard that thin in the first place? GP is suggesting that it was driven by Ive, which you dispute, but you only give an alternative explanation for the "what", not the "why".
