"Airbus did not anticipate that a pilot would stall a plane and fly it directly into the ocean"

Stalling and flying into the ground have been two common failure modes since flying began and they often happen in sequence. I would think they would be high in the list of misuse cases any aircraft designer would consider.

"we should refrain from being quick to judge which is more or less intuitive."

We should not be quick to judge which UI is more effective, but by definition we can be quick to judge which is more intuitive. In fact, the more time you spend with a system, the less qualified you are to comment on whether it is intuitive. Judging whether a UI is intuitive should take very little time and no expertise past understanding basic operations. I'm certainly not qualified to judge, but I'd think anyone who has experience with modern flight systems would be qualified to comment on whether a particular design was intuitive.

I think he meant "stall a plane and keep it stalled for many minutes, flying it into the ocean". Stall/spin accidents are common, but they normally arise from loss of control at low altitude when there's not enough time or space to recover.
