You can state the math, but not why it won't discuss various topics, etc. Once you see the models waffling on subject with objective truths. You wonder what else is wrong.
I do not exempt US models from this. They do it too, ask anything about politics, elections etc. And they can get... weird.
It doesn't take much to create a systemic error class in a model at these scales. And history has shown nation states are willing to do these things.
Just be wary.
