>I was under the impression that MCAS only controlled trim
You said "it manifests" as in situ, and in situ the pilots knew nothing about MCAS. You are continuously injecting present day understanding into the past and then impugning the pilots for not having that same knowledge. It's perverse aside from being anachronistic.
>Lion Air maintenance seems to have failed to replace/fix the AOA sensor
This is more fact free commentary. Why bother? I'm not sure how you've read the KNKT preliminary report on Lion Air 610 when you make such a baseless assertion. It explicitly says it was replaced and tested per manufacturer recommendation.
>They had 7 minutes from reporting flight control problems to the crash.
And what's your point? That in your non-pilot experience it is inconceivable that a plane couldn't be stabilized in 7 minutes and the pilots never arrived at effective troubleshooting state of mind?
Maybe instead of speculating about things you know nothing about and injecting the present as a way to judge the competency of dead people, you'd be better off reading the entire 223 page Air France 447 final report? You can speculate all you want as you read how all of your preconceptions and assumptions are wrong and why.

I meant this as a "this is what the issue was" sort of way, and thought that you were suggesting that the Lion Air or Ethiopian crashes had been caused by elevator failures.

It was more from some things I had remembered reading a few months back (after that report came out) suggesting that the replacement part was not a known-good-from-manufacturer part and that Lion Air had a history of improper/insufficient maintenance. If that was wrong, I apologize.
(Also, interesting report - no one ever really talks about the other sensor failures)

The fact that the crash took 7 minutes was intended as a counterfactual to your assertion that the pilots did not have time to diagnose anything. Since my impression of CRM in an incident was "one person flies the plane, one person diagnoses the problem, communicates with ATC, and checks procedures". Again, if this is wrong, I apologize.

This is rather insulting, but ok. I'll admit I've never read that entire report, only summaries. Might be worth a night at some point. But I'm not sure that that situation could be entirely blamed on the manufacturer either... Yes crews fail, yes that has to be prepared for by the manufacturer. At the same time, there's a reason that accident investigations attempt to avoid assigning blame and instead try to identify improvements - and at least part of that is that accidents happen when all sorts of issues happen at the same time.
