Bigcorps are veto-driven as no one wants to be the one to kill the cash cow, and VPs will do unethical things as long as they are legal and benefit the company + their immediate team, justifying it as 'good business leadership.' So jailtime and meaningful fines shifts burden from 'a fee smaller than your bonus / company profit' to 'oh shit.'

Truly bug and evil stuff happens, but most normal VP politics has email + file trails due to design docs, legal agreements, etc. Harder part seems like knowing what to subpeona and in time :)
