Does that say Camus had his phone seized? He was denied being allowed to come and speak, not to visit as a journalist, which also strikes me a fairly different case (whatever you think of his positions, or whether they should be debated or silenced). It seems unlikely to me that a journalist who'd written flattering things about the AFD would be treated so badly trying to visit Germany?
Complicated thing: had a certain Austrian who complained about the German government silencing him instead been deported and forbidden to return after his prison sentence, the world might have been a very different place.
