This is why in a free/profit driven market you *absolutely* need strong regulation. A companies mandate isn't to make the world a better place. It's to make money. The government's job is there to make the world a better place (generalisation of keep balance, keep people safe, etc).
Australia gets given grief for being a nanny state, but it's what's required.
