Nobody knows how the weight shift proceeded, the vehicle may have had the parking brake set, the tie downs may have let go at varying rates, cargo stacking could have affected the weight transfer, lots of variables.

Did you read the NTSB report? Parts from damage to the aircraft from the shifting vehicles was found on the runway near the rotation point. There was also a plume of liquid seen on video that was probably hydraulic fluid released by damage from the vehicles.
Go ahead refute my point. I’ll stand on the fact that no one knows how the weight shift proceeded including the NTSB. So postulating the plane climbed through the stall is pure conjecture.
