Do we live in a world of airplanes of all makes and models probabilistically falling out of the sky as a guaranteed characteristic of airplanes?
If so, yes, focusing on debugging a 737-MAX crash that happened to be completely full and hit an occupied building on the ground (therefore extra horrific/attention-grabbing) would be pointless.
Doubly so if the evidence required to root cause it was evaporated upon impact.
Triply so if people decided they had to know what caused that specific crash before they could address the probabilistic falling of airplanes out of the sky.
