The first line reveals the most important question in the article:
>"The Danish state is moving in an authoritarian direction by charging whistleblowers under sections of the law that should only be invoked against traitors."
The question of who is a traitor is (somewhat) answered later in the article, but I see the answer as unsatisfactory. The real question is that of political authority: does the government have a right to coerce, and does the populace have a duty to obey. It is my view that Michael Huemer answered these questions best: https://en.wikipedia.org/wiki/The_Problem_of_Political_Autho...
