Indeed. While I was surprised by the name, I quickly noticed that this was a vibes-based reaction.
I'm British by birth, I grew up with news stories about the IRA, and the second-largest city in Northern Ireland is either "Derry" or "Londonderry" depending on if you're a Republican* or a Unionist.
The English Channel, if you're French, is La Manche.
And if Germany was "renamed" by another country, it would signify a shift of something. Just like the difference you mentioned are based on massively important historical events.
