Amazon warehouses are Tilt-Up Construction. Basically 4-to-6-inch thick cast concrete panels on a grid on metal tubes as joists. Support pillars with basic trusses, and a roof tying it together.
You lose a ton of stability once that roof is gone. You lose a truss or a few pillars, and I'd imagine it came down like a house of concrete cards very, very quickly after the first wall section fell.
It has no chance against a tornado direct hit. You need a dedicated shelter structure for that.

You know what else is tilt-up? Most big box stores. Not sure why Amazon is being singled out here as I’m sure this building complied with all local building codes.
