If you actually read into the case it's more complicated than just it's Airbus fault. It was caused by one of the confused pilots input. Why they were confused is a complicated story.
Indeed. See here for a decently in-depth analysis: https://admiralcloudberg.medium.com/the-long-way-down-the-cr... .
That particular failure mode would have been impossible in most other planes including all Boeings. 1. Pretty much only Airbus doesn’t have linked controls 2. Pretty much just airbus changes what the controls allow you to do (the “law” as they call it) without input from the pilot.
No other airliner make on earth could have suffered that accident. It would have been extremely obvious what the issue was, and how to solve it on any other aircraft I can think of. This was like a car crash caused by the computer changing how the steering wheel worked mid drive.
I still have no idea how Airbus didn’t catch more flack for that design.
