This makes no sense. First, getting technical details wrong has nothing to do with vilifying hackers. Some journalists get technical details wrong. Some journalists vilify hackers. These are independent facts and linking them is terribly unsound logic.
Second, if you're a journalist, you are pretty much guaranteed not to be an expert in the fields you report on, because you're a journalist, and not a networking engineer, or a software developer, or a doctor, or a lawyer, or a professional in whatever other field you might be reporting on. Journalists have an obligation to report factually and correctly to the best of their ability, but they are not infallible.
Also, the technically incorrect piece of this article seems pretty minor. I don't understand why some people are getting so worked up about it.
