There's absolutely no reason to believe training data scraped from wherever is convenient is some neutral baseline.
If you agree with my take on censorship above, I find it hard to accept that the models today are anything other than censored. This is really obvious with pictures where you can tell that the model generated a picture, looks at it, and decides the generation is not appropriate and gives you a "I can't do that" message.
Censorship is also evident in the intent. When models are trained the intent is, presumably, to get the best data. When RLHF and similar methods teach the model not to express certain opinions the intent is clearly to avoid offense or violating political correctness. This is a classic case of censorship.
