Imagine a Russia-friendly party getting elected. Doesn't have to be overtly pro-russian. Can be someone very nationalist like Marine Le Pen in France. Or socialist like Sarah Wagenknecht in Germany. Just someone with financially dependent on Russia, or simply owing them favour.
Now imagine them accidentally leaving some loophole in the system, such that Russians get read or maybe even write access to data.
If they get elected they can fuck everyone over the exact same way.
The fact that there's something akin to a unique identifier or that it has a corresponding certificate or some means for authentication will and does not stop any malicious government. Never has, has it?
