Think about who actually suffers if you punish a company in this way: the customers, and the employees, most of whom did nothing wrong. That is not justice.

Punishing people for something they did not do is wrong, period. And collective punishment is widely regarded as a violation of basic human rights -- it's even banned by the Geneva conventions!

Furthermore, the possibility of such a punishment would have a chilling effect on business to an extent that would seriously damage the economy.

For all these reasons, no responsible government would enforce that kind of punishment on a company, and even if they tried, it would be struck down in court.

Punishments for a lot of corporate rule breaking are viewed as a "slap on the wrist" because sometimes the rules that were broken just aren't that important. Similarly, we don't usually put people in prison for speeding.
