As discussed in that thread, the flight data clearly show a type of IMU failure that has appeared in a few
Mavic 2 incidents. Even though their first-line support mis-diagnosed the issue (not uncommon), DJI has replaced at least a couple of aircraft that exhibited similar failures. In this case the aircraft wasn't lost, and so there was no replacement needed.
As for the video, the OP appears to have misunderstood entirely the explanation for the immediate cause of the flight behavior - specifically the high-speed excursion and the lack of control during the event. I have no idea why he goes on about KP indices, GPS issues, compass calibration, IMU calibration or ESC errors - none of those had anything to do with this problem. And I'm not clear what he wants from DJI - the aircraft behaved strangely and then recovered.
Lastly, even though I provided him with all the information needed to communicate the problem clearly to DJI, he appears to have so badly confused the whole thing that it doesn't surprise me that DJI are baffled.
