The resilience of ARPANET was influenced by CYCLADES, which was developed in French Academia: https://en.wikipedia.org/wiki/CYCLADES

> The CYCLADES network was the first to make the hosts responsible for the reliable delivery of data, rather than this being a centralized service of the network itself. Datagrams were exchanged on the network using transport protocols that do not guarantee reliable delivery, but only attempt best-effort [..] The experience with these concepts led to the design of key features of the Internet Protocol in the ARPANET project

Keeping with the theme of the thread, CYCLADES was destroyed because of greed:

> Data transmission was a state monopoly in France at the time, and IRIA needed a special dispensation to run the CYCLADES network. The PTT did not agree to funding by the government of a competitor to their Transpac network, and insisted that the permission and funding be rescinded. By 1981, Cyclades was forced to shut down.
