"...stupid prejudice..."

The claim that data on networks isn't completely and totally controlled by network owners is based on what? Do I need to provide some link to examples of physical infrastructure being utterly and completely permissioned? All data on physical networks can only pass by permission of the network owners. It is not possible to infiltrate data onto a physical network the owners of that network exclude (without physical access to the network), because they can physically force the data into filters that exclude any data they do not want on their network.

How do you not understand this?
