These companies do awful things because:
1. They have few viable alternatives so ethical consumers end up choosing them when they might not otherwise.
2. They have enough money that it is profitable to do bad things and pay for the damage control.
3. They have enough power to defeat regulation and government oversight.
4. They are so large and monolithic that they can hide their internal workings more easily.
5. The org chart is so deep that those in power are psychologically removed from much of the consequences of their overpowered actions.
