You want the simple answer ules? Emirates and Singapore are having the same or similar problems.
To a certain extent, that is true. But their problems have not caused them to cancel flights to the extent of QF's. Q's engineering planning guys do preventive MC by foreseeing problems that might happen and doing inspection on them or replace known trouble giving components before they start giving problems. Just look at a SQ A380 arriving at its bay at SIN and you will see a battalion of MC vehicles standing by.
But if they are changing and inspecting components outside the normal maintenance schedule then this will make it an expensive aircraft to run.
