yeah Nazis used this to legitmate their claim to be over everybody else.

and it is illegal in a way:

On 7 March 1990, months before reunification, the Constitutional Court declared only the third stanza of Hoffmann von Fallersleben's poem to be protected as a national anthem under criminal law; Section 90a of the Criminal Code (Strafgesetzbuch) makes defamation of the national anthem a crime, but does not specify what the national anthem is.

That is from your quote.

But anyway: This is about the German Team, which did a impressive job yesterday. I really hope to see some of them being future stars.

If you re-read your quote you'll find out, that this is about protecting the 3rd verse, not forbidding the 1st verse.

The problem with the hymn is the historical context. Germany is quite a young nation, just founded 1871. The text of the hymn was written in the 1840ies, when the land-marks they where talking about, where simply the landmarks Germans lived within. But yeah this has been misused.

Btt.: you'll hear from many of them. Keep an eye on the goalkeeper Manuel Neuer (1st keeper at Schalke 04 for over 2 years now, 1 A-national-team cap), defensive-midfielder Sami Khedira (VfB Stuttgart), the offensive-midfielders Mesut Özil (Werder Bremen, 1 A-cap) and Marko Marin (moving to Werder Bremen, 6 A-caps) and the defenders Benedikt Höwedes (Schalke 04, made it into the first team last season and stayed there) and Mats Hummels (Borussia Dortmund).
