Think about this

1) Newest airplane so likely upgrades everywhere so takes many hours to become familiar
2) By design as we are now learning minimal new required training to enable fastest certification and also what many of the airlines wanted this to enable max flexibility around flight crews
3) Third world ( sorry just the expression ) likely minimal to no training on differences, less experience, less hours, etc. etc. and as we now learn planes with optional safety features NOT purchased
4) Takeoff always plane is heaviest, minimal altitude, near stall, not a long of time when things go crazy to diagnose, correctly assess and correct
5) At least with Lion Air we now know they failed to fix the mechanical issue that resulted in repeated issues and prior flight had additional independent help to rescue them. You'd argue if corrective PM was done the flight that crashed wouldn't have as the failure would have never happened. Could argue with more experienced crew they'd always detect and switch of and override the system. Who knows how many undocumented events like this have already happened and suppressed.

For Ethiopian Air the jury is still out but the air track data now is indeed worrisome and what finally drove grounding everywhere.

One could argue a well trained crew, experienced pilot in a moment of such an emergency if he does the "right" thing would have avoided a crash. But if BA says safety is job one then everything they could do they should incorporate into the system; confusing switches, lack of redundancy, NOT revealing software control explicitly, offering additional safety features for this but charging extra sounds disingenuous to the comment of Safety First. Seems to be "good enough safety" but schedule and $ and pleasing customers at equal priority, and it is indeed how it is in the business world.
