"Wer öffentlich, in einer Versammlung oder durch Verbreiten eines Inhalts" means who publicly in a gathering or by distribution of the content.

"die Bundesrepublik Deutschland oder eines ihrer Länder oder ihre verfassungsmäßige Ordnung beschimpft oder böswillig verächtlich macht"

You cannot insult the state or maliciously disparage it.

Browse the other "stories" on that news portal and it becomes clear that it is a right-wing populist click bait portal which tries to incite rage against the German state by hand-picking stories and amplifying them similar to tabloids like Bild. I wouldn't be surprised if half of the stories on that portal are mostly made up or half-thruths.

PS: it reads exactly like Bild because apparently this is the new project of Julian Reichelt, former head honcho of Bild, who was kicked out because of (TL;DR) being a bigger asshole than even Bild would tolerate.
