It was technologically impossible to integrate code from outside developers into their network. As explained by Zittrain, an end-to-end network Was only possible after the development of the WinSock socket. Leaves the network simple and leaves as much of the computation as possible to the devices at each end. Only works in closed, proprietary networks.
