> seems to amount to about 20 lines of code

it's sobering to think that 20 lines of code could potentially have saved 346 lives :/

That doesn't sound right. If I understand correctly, the crashes were not due to a programmer making a mistake in a few lines of code. They were due to inadequate sensor redundancy, inadequate pilot retraining, and possibly a missing warning light [0] (the fault still lying with Boeing on all three points). At no point did the behaviour of the MCAS software deviate from its specification.

Deactivating MCAS on AOA disagree would have prevented both crashes. But yes, the program behaved to spec, so strictly speaking it is not a programmer error but a spec problem.
