[ambivalence]

There are three related terms: mocking, faking, and stubbing. They mean subtly different things, which the article points out. The author prefers the last one, and uses the middle one for complex cases, avoiding mocks altogether. But that doesn't mean he leaves third-party networking libraries run wild in unit tests. In fact, the very example he builds in the article shows how to avoid that without having to create a mock. Maybe you need to read it again?
