The article never defines GDR, but I looked it up in case you were also unfamiliar:
The German Democratic Republic (GDR), commonly known as East Germany, was a socialist state in Central Europe that existed from October 7, 1949, to October 3, 1990

Look at radio stations. We have SWR: Süd-West Rundfunk (south west) in Baden-Württemberg and Rheinland-Pfalz. We have WDR: Westdeutscher Rundfunk (west) in Nordrhein-Westfalen. We have NDR: Norddeutscher Rundfunk (north). In Niedersachsen, Schleswig-Holstein, Mecklenburg-Vorpommern and Hamburg (not Bremen).
... and then we have Mitteldeutscher Rundfunk (middle) in Sachsen, Sachsen-Anhalt, Thüringen.
And no one is in the east ...
Actually, if you look at the map of German regional public broadcasters (https://en.wikipedia.org/wiki/ARD_(broadcaster)#/media/File:...) and squint a bit, the MDR is more or less in the middle: more on the north-south axis and less on the east-west axis (with only the RBB partly more east), but still...
There was the ORB - Ostdeutscher Rundfunk Brandenburg. Which later (2003) merged with SFB - Sender Freies Berlin to RBB - Rundfunk Berlin Brandeburg.
Thus the middle serves the middle. And while Saxonia (Part of MDR) indeed goes to the east most point of Germany it's at least middle in North-South. But the most middle point (depending a little on exact definition) is in Thuringa (also part of MDR)
This negative psychological disposition towards your own collective identity is a profound cultural disorder (at the level of mass psychology). It is wide-spread and even mainstream in Germany among the left-leaning. Significantly, it has never been the object of public debate, as public debate is strictly controlled by the adherents of this perverted ideology.
* "SBZ" -> Sowjetisch besetzte Zone -> sowjet occupied zone
* "Ost-Zone"
* "DDR"
* "Ost-Deutschland"
Almost no one spelled out "DDR" with "Deutsche Demokratische Republik", since that was a lie. There was little democracy there.
People that fled from east-germany early (e.g. before the wall) usually used "SBZ "or "Zone". And it was usually meant in a derogatory sense. "DDR" was more neutral, although few people in west-germany had a neutral view on the eastern regime.
And in the UK. Presumably because it was used in athletic meetings and on cars. Never seen 'GDR', we'd just use 'East Germany'.
Side note: I find it amusing that countries that have a need to put "Democratic" in their official name are never democratic. DR Congo, Democratic People's Republic of Korea and Deutsche Demokratische Republik. Why even bother, it's not like anyone is looking at the name and go: Yup, that's a democracy.
