All things made by humans have some level of bias, there is no escaping it but as for deliberate bias and censorship. Those are business decisions made by business people.
Was there a difference between a biased or unbiased LLM? not one worth mentioning, I have tried both types and I haven't seen a difference in 90% of my output unless I am specially trying to hit a bias.
Which would I use for work? Neither, because my work is specialsed enough that the hallucinations LLM produce cause more problems then the boot strapping solves.
