Problem is software engineers are replaced with juniors/contractors that probably do not know any better and are only one part of a system that has failed in its entirety.

What sane person would willingly put up code that can kill others on purpose... so we're left with incompetence.

Accountability, if implemented, should be company wide.

Right now issues have passed design stage, implementation, qa... with this sort of failure you have management to blame for not putting up processes in place so its caught / hiring and keeping competent enough people.

This is sort of expected as they optimized cost to the detriment of everything else.
