This line of argument only works if the majority of a company is exposed to illegal behavior.
If a large company can commit (or attempt to commit) illegal behavior, while making that behavior only visible to a small fraction of people, then this argument falls apart.
For example, how many people were involved and aware of the VW emissions scandal? 200? 400? Out if 200,000 worldwide employees. So >99% of VW employees would have likely reported not having observed illegal behavior. That does not mean that those employees “lucked out” into working for an ethical legally-compliant company. It means the company is smart enough to hide its unethical and disreputable behavior from its employees as much as possible.
