Although the aircraft 'cannot stall' the landing was so hard that an undercarriage leg went up through the wing. Stalled or not that aircraft virtualy fell the last few feet
The above is a kind of subjective (eyes of the beholder) support for your argument in my view.
To my knowledge nobody has published the vertical g rates for the landing suggesting that it "fell" out of the sky. The track of the landing gear suggests that it was a lateral force that broke it as designed, from ploughing through the soft earth along the flight path.
Of course there is plenty of room for discussion here (CRM) once the facts are released.
