The AOL case wasn't merely about spam--you can't pretend that it was. Here's part of the opinion:
> By providing its members with access to the Internet
through its e-mail system so that its members can exchange
information with those members of the public who are also connected to the Internet, AOL is not exercising any of the municipal powers or public services traditionally exercised by the State as did the private company in Marsh. Although AOL has technically opened its e-mail system to the public by connecting with the Internet, AOL has not opened its property to the public by performing any municipal power or essential public service and, therefore, does not stand in the shoes of the State.
