Hypothetical: If an employee in McDonald's overcharges all the customers do you think that McDonald's/the franchisee is completely devoid of responsibility because it was "just an employee"?
That's a good example. But there's a difference between harming your customers and harming your competitors. In the case of McDonalds' hypothetical actions, the solution is to give your customers their money back and a few free burgers. But what can Google do to make up for their mistake here? Go back in time and not hire the individuals that fucked up?
