Luoto, I disagree with what you said about nationality.
With, say, less than 20 Danes working TWR/APP or ACC in Zuerich, by disclosing nationality (let alone releasing other details) Skyguide made it far easier for the media to identify the controller concerned.
There is no reason to expose a controller to the media circus. Any judgement should be from the results of a fair investigation NOT poorly informed sensationalism.
