Children born in Germany to non-citizens can get German citizenship under certain conditions only since January 2000. I’d assume your mother is older than 25, which means she wouldn’t have the right to German citizenship just because she was born in Germany and therefore neither would you. Do you know for a fact that your mother has dual citizenship?
You can always find someone pressuring for anything. I’m not a huge fan of the incoming government coalition but there’s no doubt of their support for Ukraine. They are currently negotiating how far they will extend the support, nobody is talking about reducing it - at least not in the negotiating parties.
The only thing called into question is the extent of monetary support for Ukrainian refugees. They currently have a similar status to EU citizens, there are talks to reduce that status to the same level as other refugees. We’ll see what the results of the negotiations will be.
