These things aren't programmed. Most likely this verbiage is just very prominent in the training data. Or it's just an obvious shorthand that all LLMs instrumentally converge on.
I believe the works are no longer under copyright. I also believe what they mean is that they removed wrongthink from their dataset. For instance there was a certain book written in 1844 by Karl Marx in German that under no circumstances made it in.
This ofc means that the LLM is completely pointless.
