What happened can be deduced with high confidence, we certainly don't have enough facts to determine why it happened.
My only reason for speculating or reading the posts that speculate is trying to make sure I don't do the same thing or something that others postulate could cause such an issue. At this point, nothing seems obvious to me outside an initial failure of some sort.

And now we are on the microburst theory🙄🙄🙄🙄.

I've had automation do glitchy things, but it always did it relatively smoothly.

There has been some dumb things posted here for sure, but you’re barking up the wrong tree here.

This NTSB update and latest WSJ article doesn’t make sense to me. Fair amount of 121 flying some in this model. Never have I seen anything this dramatic, whether inadvertent or not, with regards to pitch input. Never. Actually it takes some effort to get 121 guys to get this aggressive with a big airplane. Engines never spool up so quickly to catch me off guard and I’m no ace of the base. Seems implausible.
And as far as automation doing this...still makes absolutely no sense.

Just going to throw this out as a idea...what if they thought based on erroneous information that they were in a nose up up unusual attitude in IMC...they added thrust and pushed to bring the attitude indication to level flight. Obviously this raises questions about crosscheck or what else was going on, but it would provide an explanation of advancing thrust and aggressively pitching down.

Flying through the downdraft alone would not cause that chain of events.
