 Rx is designed in the style of functional programming, but it exists within an object-oriented environment. We also have to protect against object-oriented dangers. Consider this naive implementation for a service that returns an observable.

 The code above does not prevent a naughty consumer from changing your `items` with one of their own. After that happens, subscriptions done before the change will no longer receive items, because you are not calling `onNext` on the right `Subject` any more. We obviously need to hide access to our `Subject`

-The first subscriber is the first to be called for each item. Its action is to modify the data. Once the first subscriber is done, the same reference is also passed to the second subscriber, only now the data is changed in a way that was not declared in the producer. A developer needs to have a deep understanding of Rx, Java and their environment in order to reason about the sequence of modifications, and then argue that such code would run according to a plan. It is simpler to avoid mutable state altogether. Observables should be seen as a sequence notifications about resolved events.
