Well, she was also fired (finally) and her career is finished. I agree it was monumentally stupid. But "punished as high treason"? Treason requires intent. She most certainly did not intend to be criminally disloyal to the country. Merely being ignorant and incompetent is not treason.

This is a major fuckup but let's be real. Our country is a "joke"? I know complaining is a national sport in Sweden, much like in many other countries, and I can rage about plenty of idiotic things going on. But on the whole, things are in general pretty good, relative to most other countries in the world. Move elsewhere and you'll just find a different set of things to be mad about (perhaps more, perhaps less; and there's always a bunch of Swedish expats who complain that things don't work like in Sweden).
