You can hire people to pay them money, even if the money is very attractive, but you can't buy their heart and mind, everyone thinks for themselves and not all these crypto projects are bad, some hacks and backdoors happened as an inside job.
But lack of competence and maliciousness are 2 different thing. OP thread is about programmer's competence.
Weak security and getting hacked are still their fault though whether due to lack of competence or intentionally add security flaw.
