So what do you think they're in business for? Their health? Besides, power doesn't make a profit. What makes a company profit is offering/delivering the consumer something he wants and at a reasonable price.
Pepsi-Cola, Sony and British Airways can't force you to use thier product. They don't have the power. Only the goverment can and will force its product on the consumer. It is only governments, not industries, that have "thr power".
