I'm going to need a source on that. As someone living in Germany (am Dutch), I've never heard of this. Either the government is good at controlling the media, the media don't care, or it's not happening, and the latter seems most likely to me but if you have (a) reliable source(s) I'm fully prepared to learn something new and be convinced.
