A key development that accompanies and enables proprietary systems is cloud computing, wherein each of the giants stores vast amounts of material on their battalions of servers. users do not need to have massive computer memories to store their own material; they can—indeed, must—access everything they have from a small device just by gaining access to the cloud. There are still “little guys” who offer hosting services, and that is a constructive activity. At the other end of the spectrum, though, the digital monopolists, including Google, Facebook, Amazon, Apple, and Microsoft, have all invested to build enormous private clouds. Cloud computing is a brilliant way to make the Internet more efficient and less expensive to users and society, but whether having the preponderance of cloud capacity in the hands of a few giant firms is a wise policy is another matter altogether. The clouds can be a treasure chest full of valuable data for the giants to exploit.
