Because you bought content on the internet.
Contrary to popular belief, content on the internet is not free. You have always paid for content on the internet: You give up your anonymity when companies view your user profile. Or you paid with your attention to advertising. The creators of all this content want to make a living from selling their work. And every company distributing content will use its sales revenues to pay its employees, as well as to create or buy new content.
LaterPay offers content providers an option to sell their content in a transparent way, at fair prices.
