From reading the report, the FCPC commanded a pitch down for 2 seconds, during which time the captain was unable to counteract the pitch down using stick back commands. Thus this incident was due to erroneous protection activation, which the flight crew was unable to override.
this is the key difference between the 777 indicidents and the A330 incident.
Obviously both systems are very safe, but the efficacy of flight control systems, should, IMHO, be continually reevaluated and changed if required, and this report seems to well serve this purpose.
