It would be difficult to change (and guarantee) the behaviour of thousands of pilots flying a particular type, but it is easier to change the logic of the auto throttle system in a few hundred aircraft, and at a lower cost (but who's cost?).
Technical cost now vs escalating damage to the product name.
Perhaps in this accident we have the one operator who has sufficient 'clout' to persuade the manufacturer to think again.
