Why do you think Apple sent the Vice President to such a high visibility trial and not the President, who is the person with the ultimate authority and accountability in Finance?
In any large enough organization (and I haven't stumbled on one where this wasn't the case), private or public, the people at the top are shielded by a "second in command" whose job is to take the hit if needed, with the promise that they're next in line for the big position. It's a requirement of the job, they do it and maybe get rewarded, or don't and absolutely get ejected. Sometimes it pays off and they get the coveted president, CEO, etc. position. Sometimes it doesn't and they go to prison or their career is completely derailed.
Survivorship bias says we only see the ones who managed to pull it off. If you look at any large company's CEO now, they're there because they took these hits or provided plausible deniability for the big boss in the past.
