Money makes money. Say they raise enough to earn interest on their capital. Say they make 1% interest per year. Storing a GB costs $10. 1% of that is 10c. How much does it cost to store a GB for a year? Amazon charge ~1c/m for infrequent access and 0.4c/m for Glacier. So somewhere between 12c and 5c a year.
