Are those really that different? Sure, the manifesto spends more time showcasing the benefits of a reactive system than explaining how it works, and that explanation takes the form of an event-based view.

But event propagation ''is'' a way to transfer change throughout a system built on data flows, so it fits the definition of the reactive parading. In doing so, the manifesto could be seen as a particular way to realize RP, a subset of a larger concept.

Am I missing something? Why do you consider they don't have anything in common but the name?
