From what I remember, there wasn't an input "conflict" on 447. The flying pilot was pulling back on the controller, but the opposite pilot's control doesn't mirror that, so he wasn't aware that he was. That, coupled with the stall horn likely confusing things, seems to be at the root of 447.

This crash likely has nothing to do with 447 or fly-by-wire. Plane reaches fl380, is there for a couple minutes, and begins a 3000fpm descent. No communication whatsoever. Something, hypoxia or ... disabled the flight crew, probably after they managed to initiate an emergency descent. Plane would have likely flown on except for the height of the surrounding terrain. Most of the pilots over at pprune seem to think it was some sort of explosive decompression. That leaves open all sorts of scenarios.
