Why is all this necessary? Because traditional service providers earn their revenues
through services provided to their subscribers. This is a significant departure from the
Internet business model, which operates as a free enterprise, with companies earning
revenues through advertising and value-added services rather than access. The
Internet companies of the world in fact do not worry about access, because the telephone
companies and Internet service providers (ISPs) provide this as part of their
service offerings.
What happens, though, when the very telephone companies providing access to the
Internet also attempt to provide their services and applications in an Internet model?
The mechanisms required by telephone companies to bill for their many services, and to
ensure that the network is secure and operating at its highest efficiency, are no longer
available.
For example, on the Internet, one can send an e-mail anonymously, using one of
many different anonymous servers on the Internet. And the e-mail service is provided
at no charge (look at Yahoo, for example). Now imagine a telephone company using the
same model, with no means of recovering its investments in the e-mail platforms, and
no means of tracing and validating the originator of the e-mail. In fact, imagine not
even being able to determine if the subscriber sending or receiving the e-mail is even
authorized to use e-mail services.
