The rise of the internet moved us from the feudal structure of a centralised network where one node controlled and communicated information to all other nodes. We moved to a system of decentralised nodes where all nodes are equal in both contribution and receiving from all other nodes. This means there is no one central node to be taken out that will destroy the network as illustrated below:
But this is being undermined by big data, EULA and IP rules that seek to limit the copy machine that is the internet. They try and create what can be referred to ass walled gardens where only there approved items exist. this is very similar to the original concept of a walled garden in networking as a network that can only communicate within itself but has the added fact that the network has a centralised controller mechanism.
