The arguments and opinions that I have been reading in this thread seem to be presumptious of the facts.
There is a difference between "an engine problem", an engine failure and an engine that needs to be shutdown. Part of this are engine out of limits ECAM warnings requiring a pilot action and/or discretionary action by the pilot to simply retard the throttle.
To divert or not divert has to consider what are the facts as the pilot sees them and not what the press says or we imagine.
To me it's a complete waste of time for us to second guess decisions when we don't have access to the DFDR.
Of course I'm still interested in whether this was a common fault, independant faults, engine performance faults or aircrat or engine electronic control functions.
