The author is begging the question, rather than creating a false dilemma.
Begging the question: the premise assumes the conclusion, e.g., "that's illegal because it's against the law".
False dilemma: you present two possible options as the only options, when in fact there are other alternatives, e.g., "either you're with me or against me"
The article never states these are the only two options. I don't know why that conclusion is being drawn. But everyone has a right to their opinion so I can't stop people from making their own assumptions :)
