Gmail shows me ads related to the content of my email. Worse, it shows ads related to the content of emails sent by my friends and family.Some of which have no relationship or agreement with Google. Google does this to maximize advertising revenue. Google is profiting off the original works of my friends and family without their permission and provides them absolutely nothing in return. Now you may complain about the moral and ethical practice of distribution rights. But sharing with people you know is not distribution. Most countries have different laws for sharing then distribution. In my country it is naturally legal to share music and other recorded content. Your country may convince you that this immoral, but in the natural sense, sharing is never immoral. In fact it is compassion.
