You are forgetting the active flight control system, which is controlling the flight surfaces and more-important than secondary factors from drag. (See Post #59).
I’m assuming that the flight control surfaces (FBW Flight control) reacted in ways that helped the plane stall.
To be clear, I’m not stuck with the theory that extra speed caused the stall. It could just as well have been less speed, or the results of 100mph winds from a totally unexpected direction.
My main point is that it seems this crash was a result of weather conditions, and maybe some equipment malfunction.
It does not seem like a terrorist bombing, but then these things take time to get all facts possible.
