It was snarky, and I expected the down votes. But, I think it needs to be said. Neither I, nor the OP, have enough information to make any conclusions. It is just a lot of observations, rumors, and opinions.

I love speculating about everything from government policy to interpersonal relationships. (It helps me validate my mental model of the world.) But, in this case, I know the NTSB currently has a better picture of the situation than anyone on the internet.

They'll make a preliminary, primarily "factual" report within days, or weeks. This will be based on the FDR, Quick Access Recorder, statements by crew, passengers and witnesses to the NTSB investigators.

Even though I'm a former pilot, I've not made any posts prior to this one, because I didn't want to speculate.
