Those questions are used as a canary for government manipulation because it's a known topic.
Assuming that the manipulation and censorship only covers a few obvious historical topics and leaves everything else untouched would be very naive.
The fact that it’s a canary makes it a prime tool for A/B testing of generalized approaches to censor or “secure” a model.
I don’t see how that responds to the point in the parent comment. Censorship or not, chatbots are unreliable for serious history questions.
Just today Gemma told me that for a long time the Iliad and Odyssey were considered mediocre literature. I was skeptical so I cross referenced, but a lot of more subtle errors could get by.
