Did I read that right?

This is from the Amicus brief of the United States:

Unlike traditional Internet transactions, in which a user’s computer obtains information from a specific website operated by a central computer “server,” P2P networking software gives users direct access to the computers of other users on the network.

Did I read this right? Since when is there a traditional Internet transaction? I thought the internet was really a decentralized network of peers, where information would get from point A to point Z while traversing a series of other points along the way, where everybody has an address (IP) and where nobody had really more importance then others in terms of what they can do (with obvious exceptions like controlling a top level domain, or being some kind of backbone, etc.). On top of that, I am not sure what they base "tradition" from. Is it from the latest b2b site? the dot com boom b2c sites? It's really funny how they frame this.
