Good point about the use of exclamation mark at the end of imperative sentences in German. The article leads with Adorno's quote:

> sociologist Theodor Adorno felt the ! signified an “unbearable gesture of authority”.

Calling the exclamation mark a sign of authority makes a lot more sense if one knows that in the native language of Adorno, it is a grammar rule to use it at the end of an imperative sentence.
