“If… the protection of intellectual property is eroded, that hurts everyone. People need to have
the incentive that if they… succeed, they can make a fair profit…. But on another level entirely, it's just wrong to steal. Or, let's put it another way: it is corrosive to one's character to steal. We want
to provide a legal alternative.”Steve Jobs
