IMHO everyone is entirely missing the point pointing their finger at Boeing.
The main issue is the FAA and how it failed to control Boeing. It’s obvious a business will try to sacrifice safety for money. But there should be check and balances. Someone making sure a business doesn’t do that.
The FAA let Boeing supervise itself.
Just to be clear some of the higher up at Boeing are criminals but so is the cop that told him he could police himself.
